Splice site consensus sequences vary by species. Predicted css are shown by the vertical boxes for the indicated genes. The relative proportions of the bases T, C, G and A are shown as a percentage at five positions both upstream and downstream of the predicted cryptic cleavage site.

Vaas, Rüdiger (R.V.) Non-canonical splice sites are not detected. This proportion is smaller than the 11/14 match observed for the actin gene family (Supplementary Figure S2), but is still highly significant (P = 2.2 × 10−15, see ‘Materials and Methods’ section). To test CSF we analyzed a database called DBASS (database of aberrant splice sites), which lists 340 human genes that have one or more css that are activated in genetic disease (3). Wolf, Dr. Matthias (M.Wo.) The evolutionary implications of this finding are discussed. In the second method, an arbitrary genomic interval can be specified and CSF will return a hierarchic list of css for that interval. Culmsee, Dr. Carsten (C.C.)

However, there are only 61 cases where the DBASS and CSF css are located within the same exon or intron (Supplementary Table S1, column 5), giving a match rate of 46/61 or 75%. For those eukaryotic genesthat contain introns, splicing is usually required in order to crea… * - marks the position of css that match introns; ^ - marks conserved css. We, therefore, reasoned that css might be used at a low but detectable frequency by normal genes. Oehler, Prof. Dr. Jochen (J.Oe.) Hassenstein, Prof. Dr. Bernhard (B.H.) The 5' splice site of a pre-mRNA is recognized by U1 small nuclear ribonucleoprotein particles (snRNP) through base pairing with the 5' end of U1 small nuclear RNA (snRNA). Weygoldt, Prof. Dr. Peter (P.W.) Unsicker, Prof. Dr. Klaus (K.U.) Mohr, Prof. Dr. Hans (H.M.) The identification of css by CSF is limited by the amount of available transcript data but this will improve as further transcript sequences become available, particularly with the advent of mRNA deep sequencing (24). Cryptic splice sites are used only when a natural splice site is disrupted by mutation. Trotz Warnungen hat die EU die Arznei frei gegeben. It is unlikely that a css is recognized from the immediate splice-site information alone (8–10), suggesting that other information such as splicing enhancer sequences are also conserved between some gene homologues independently of intron presence. Based upon these results, we Of the two sets of DBASS and CSF css, only 46 are in common (Supplementary Tables S1 and Supplementary Data). Walter (W.L.) Grieß, Dr. Eike (E.G.) Single-base substitutions within a 9-nucleotide 5'-splice-site sequence can abolish or attenuate use of that site and, in higher eukaryotes, can also activate nearby "cryptic" 5' splice sites. Huber, Christoph (Ch.H.) Cryptic Splice Sites (n.) 1. Paulus, Prof. Dr. Hannes (H.P.) Cryptic splice site selection depends upon the nature of the mutation disrupting the authentic 5′ ss. We also report a fascinating correlation between the positions of css and introns, whereby css within the exons of one species frequently match the exact position of introns in equivalent genes from another species. Riemann, Prof. Dr. Dieter [mno] In the first method, a landmark EST accession is submitted and CSF returns a list of css within the genomic range of the entered EST. Sitte, Prof. Dr. Peter Below is a list of cryptic splice site words - that is, words related to cryptic splice site.

Stöckli, Dr. Esther (E.St.) Comparison of intron and css positions for a small part of the ribosomal protein gene database (23). Similarly, we identified 135 css in the coding region of 51 different genes of the ribosomal protein gene database. Splice site consensus sequences that drive exon recognition are located at the very termini of introns. The splicing information that flanks introns is perhaps similar to the splicing information that enables the mRNA of intronless genes to interact with components of the splicing machinery for the purpose of mRNA biogenesis, nonsense mediated decay or alternative splicing (38–43). Fässler, Dr. Peter (P.F.) Schließlich haben Delfine keine Hände. [def] This is a striking observation because although the splicing information that flanks introns contributes to their recognition, there is no mechanistic reason for this information to be autonomous rather than auxiliary in nature for the purpose of intron removal (37). tight coupling to intronic editing sites and splicing. Haug-Schnabel, PD Dr. Gabriele (G.H.-S.) The key question we have started to address here is whether such information might have been functional. Alignment of the predicted css indicates that the large majority are correct because they conform to splice site consensus sequences (Supplementary Table S4). Css were previously reported to be active at very low levels in normal globin genes (22) and our results systematically extend this finding. This is because the two types of splice sites are rather similar. 2003), and experimental work has established that splicing in vivo is possible even without the core dinucleotide GU or AG.

Rübsamen-Waigmann, Prof. Dr. Helga Drews, Dr. Martina (M.D.) In order to be considered by CSF, a gap in the alignment must be flanked by a minimum number (25 by default) of matching residues. RNA splicing, in molecular biology, is a form of RNA processing in which a newly made precursor messenger RNA (pre-mRNA) transcript is transformed into a mature messenger RNA (mRNA). Huber, Dr. Gerhard (G.H.) Von Tigermücken, Anopheles und anderen verbreiteten Arten geht ein erhebliches Gesundheitsrisiko aus. We previously identified nine css within the coding region of the actin gene family by experiment and reported an eight out of nine exact match to the position of introns in actin genes from other species (13,14). Our data also indicates that the information that lies outside some introns is not only conserved with homologs that lack such introns but is also capable of being independently recognized by the splicing machinery and can define the position of the ‘missing’ introns (13). Our previous work indicates a connection between css and introns. These results strongly indicate that many introns were inserted into css during evolution and they also imply that the splicing information that lies outside some introns can be independently recognized by the splicing machinery and was in place prior to intron insertion. CSF defines the common deletion endpoints as authentic splice sites and the unusual deletion endpoint of the minor transcript as a cryptic or alternative splice site (see ‘Materials and Methods’ section for further details). This indicates that non-intronic splicing information had a key role in shaping the split structure of eukaryote genes. Oxford University Press is a department of the University of Oxford. splice sites (Fig. However, HBB has 11 known css (Supplementary Table S1), which illustrates that CSF is limited in its predictions, most probably by the amount of available transcript data. The 51 genes are 190 codons in size on average and have a total of 957 introns (from 22 species). PCR products marked with asterisks were sequenced in order to confirm the use of the predicted css (Supplementary Figure S3). Thirty-three out of 135 css of the ribosomal gene family exactly match the position of introns in other species (Supplementary Figure S4). Mehler, Ludwig (L.M.) Probst, Dr. Oliver (O.P.) Five css predictions by CSF that DBASS shows to be activated in patients were detected in human cell lines that do not have the causative genetic mutations (Figure 3, lanes 1–5). Harder, Deane Lee (D.Ha.) Wagner, Prof. Dr. Edgar (E.W.) RT-PCR analysis confirmed both these defective Meioc exon five splicing patterns within the Rbmxl2-/-testes (Figure 5B–C). Born, Prof. Dr. Jan (J.Bo.) Winkler-Oswatitsch, Dr. Ruthild (R.W.-O.) Collatz, Prof. Dr. Klaus-Günter (K.-G.C.) Our findings suggest that cryptic splice-site activation is more common than previously thought and should be routinely considered for all variants within the transcribed regions of genes. Unlike the scanning programs, CSF cannot predict the position of splice sites that are created de novo by gene mutation. Kirkilionis, Dr. Evelin (E.K.) Sie gehörte zu den ersten modernen Menschen in Europa, die aber wieder verschwanden. splicing, introns Cryptic Splice Site | … Wild, Dr. Rupert (R.Wi.) Conflict of interest statement. This Table is compiled from 169 and 179 examples of 5′ and 3′ css predictions, respectively, that are supported by only single ESTs (Supplementary Table S1). Wirth, Prof. Dr. Volkmar (V.W.) Mutke, Jens (J.M.) It is clear from Figure 3 that some splice sites that have been classified as css are used by normal genes at a relatively high frequency (lanes 2–5), which is in accordance with the CSF analysis (Supplementary Table S2). We confirmed that css predicted by CSF could also be detected by experiment. Scholtyssek, Christine (Ch.S.) Schmitt, Prof. Dr. Michael (M.S.) A cryptic splice site is a mRNA sequence that has the potential for interacting with the spliceosome. For example, there is an intron located within a codon for valine (V) in the fungus Cryptococcus neoformans but in no other listed species. Stechmücken sind nicht einfach lästig. [ghi] Bensel, Dr. Joachim (J.Be.) As explained above, the reason why BU198526 was identified by CSF is because it forms a pattern alignment with other ESTs as illustrated in Figure 1A(ii). + 1G donor splice site mutations virtually suppress correct gene expression. None declared. Sauermost, Rolf (R.S.) Sahashi et al. Grüttner, Dr. Astrid (A.G.) Littke, Dr. habil. The probability of a css exactly matching an intron by chance is therefore 957/(190 × 3 × 51) = 0.033. Zähringer, Dr. Harald (H.Z.) There are 65 cryptic splice site-related words in total, with the top 5 most semantically related being transcription, snrnp, mrna, mature messenger rna and messenger rna.You can get the definition(s) of a word in the list below by tapping the question-mark icon next to it. Sachße (†), Dr. Hanns (H.S.) They are joined during the RNA SPLICING reaction, forming the junctions between exons. For each tuple pair returned by the query, the splice sites of the intron that has more supporting ESTs are declared authentic and the remaining site is declared cryptic. Franzen, Dr. Jens Lorenz (J.F.) Engeser, PD Dr. Theo (T.E.) The alignment of css predictions by CSF reveals consensus sequences typical of splice sites. 2020 Dec;120(6):1425-1432. doi: 10.1007/s13760-020-01513-0. Figure 1B illustrates how ESTs align to the human HBB gene for β-globin, which has two introns. Nucleotide sequences located at the ends of EXONS and recognized in pre-messenger RNA by SPLICESOMES. Before comparing the css identified by CSF with those of DBASS, we first asked whether the css predictions that are supported by just single ESTs were likely to have been generated by aberrant splicing. Pickenhain, Prof. Dr. Lothar (L.P.) For genes with many introns it is suspected that up to 50% of mutations that cause disease do so by affecting splicing, either through the activation of css, exon skipping or disruption of alternative splicing (4–7). Bohrmann, PD Dr. Johannes (J.B.) Häbe, Martina (M.Hä.) Wülker, Prof. Dr. Wolfgang (W.W.) In addition, CSF also identifies a subset of alternative splice sites that are similar to css, but are used at a greater frequency. Doch die Frage zu stellen, war sinnvoll, denn sie hat eine Eigenart der menschlichen Wahrnehmung offenbart. Jendrsczok, Dr. Christine (Ch.J.) Cryptic splice sites are used only when use of a natural splice site is disrupted by mutation. Martin, Dr. Stefan (S.Ma.) We identified a small number of css in the exon regions of actin genes by experiment and discovered that eight out of nine of these exonic css sites exactly match the positions of introns in actin genes from other species, which led us to conclude that these particular actin introns were inserted into css during evolution (13,14). Meineke, Sigrid (S.M.) We show below that css predictions by CSF are very reliable even if supported by just a single EST, as in this case. Jetzt wurde der erste Fall in Europa bekannt. The most common HGPS mutation is located at codon 608 (G608G). Neub, Dr. Martin (M.N.) Entire chromosomes can also be entered such as NC_000001 (human chromosome 1) for which CSF currently lists 3232 css. This means that CSF only lists a subset of the total number of authentic splice sites for any one gene. The deletion of the splicing site results in one or more introns remaining in mature mRNA and may lead to the production of abnormal proteins. Messenger RNA was prepared from the human cell lines K562 (lane 1); HEPG2 (lanes 2, 3) and primary mesenchymal stem cells (lanes 4–6) and used for RT–PCR with the indicated primers (see Supplementary Data). As illustrated the vast majority of ESTs align as shown and define the three exons of this gene. Where applicable, the count is followed by a number in parentheses. However, it is useful to have this type of information because alternative splice sites are also implicated in genetic disease and in this particular case disruption of the splice site at position 32 370 094 gives rise to Frasier syndrome, possibly due to the increased use of splice site 32 370 103 (20,21). This observation is typical in that although introns are wide-spread among eukaryotes, the vast majority of individual intron positions are found in only a minority of species (Supplementary Table S3) (18). Here we show that the serine/arginine rich splicing factor 2 (SRSF2) promotes cryptic 3′ splice-site (3′AG′) usage during cassette exon exclusion in survival of motor neuron (SMN2) minigenes. Jahn, Prof. Dr. Theo (T.J.) Illerhaus, Dr. Jürgen (J.I.) During splicing, introns (non-coding regions) are removed and exons (coding regions) are joined together. Zompro, Dr. Oliver (O.Z.). Yuri Kapustin, Elcie Chan, Rupa Sarkar, Frederick Wong, Igor Vorechovsky, Robert M. Winston, Tatiana Tatusova, Nick J. Dibb, Cryptic splice sites and split genes, Nucleic Acids Research, Volume 39, Issue 14, 1 August 2011, Pages 5837–5844, https://doi.org/10.1093/nar/gkr203. Mahner, Dr. Martin (M.Ma.) Splice-site activation was predicted for 129 (28%) of the pathogenic variants and 75 (22%) of the VUSs. Haken, Prof. Dr. Hermann WT1 is an example of gene that encodes at least three alternatively spliced mRNAs and for which there are only 80 ESTs. CSF was designed primarily to identify css in highly conserved gene families such as actin in order to advance our understanding of intron origin. Warnke-Grüttner, Dr. Raimund (R.W.) PCR bands were excised and cloned into pGEM-T Easy vectors (Promega) for sequencing by colony PCR followed by ABI Prism Big Dye Terminator cycle sequencing (Applied Biosystems). The well-known and valuable early and late models of intron origin both assume that the splicing machinery evolved for the purpose of removing introns that were either present in the most ancestral genomes or were inserted after the separation of the prokaryotes (25–27). Kössel (†), Prof. Dr. Hans (H.K.) It does this by identifying transcripts that have been generated through the low level use of css by normal genes. Marksitzer, Dr. René (R.Ma.) Jendritzky, Prof. Dr. Gerd (G.J.) Nemeth-Slany A(1), Talmud P, Grundy SM, Patel SB. The positions of all of these introns together with the 14 css that we have identified are plotted in Supplementary Figure S2A. Wicht, PD Dr. Helmut (H.Wi.) Jäger, Dr. Rudolf The database runs a query to detect tuple pairs satisfying the css condition: the overlapping introns match at one end and mismatch at the other, with a mismatching intron end from one tuple residing within the exon from the other tuple. Published by Oxford University Press. For splice site prediction within a sequence putative splice sites are preprocessed using position specific score matrices. The data sets included hundreds of 9-mers: sequences that are 9 bases long. This distinguishes mRNA deletions that are generated by low-level aberrant splicing from deletions that are generated by non-splicing mechanisms such as errors during transcription or during the generation of the EST. Rehfeld, Dr. Klaus (K.Re.) Das könnte Sie auch interessieren: Spektrum der Wissenschaft 5/2021. The most frequently occurring bases are shaded. Sudhaus, Prof. Dr. Walter (W.S.) Vollmer, Prof. Dr. Dr. Gerhard (G.V.) Just, Dr. Lothar (L.J.) Epub 2017 Feb 12. For genes that have introns there are still many reports of intron-independent splicing between exonic splice sites (44–53). At the time the models were proposed, non-intronic splicing information was not generally thought to be of major relevance and so is not an important feature of either model (28). (A) CSF searches for transcript alignments that form one of four patterns (i–iv). Can codon usage bias explain intron phase distributions and exon symmetry? We report that many css are not entirely dormant and are often already active at low levels in normal genes prior to their enhancement in genetic disease. Klein-Hollerbach, Dr. Richard (R.K.) However, this program provides a useful complementary resource for studies of genetic disease and it also enabled us to establish that there is a strong and general correlation between the positioning of css and of introns. cryptic splice site Quick Reference A randomly occurring site in the genome that contains the consecutive six‐nucleotide consensus sequence for 5′ or 3′ … Css are often used highly efficiently in genetic disease following the mutation of nearby more competitive splice sites. Olenik, Dr. Claudia (C.O.) Consequently, our finding that css often match the position of exon junction sequences in gene homologues, strongly indicates that css were targeted by intron insertions during evolution. Actin genes usually have 375 codons and therefore three times this number of possible positions for introns or css and so the probability of a single css exactly matching an intron position by chance is 91/(3 × 375). At least two possibilities can be offered to explain the f3-globinthalassemicsplicingphenotype.First,thedecreased useofthe5' splice site andconcomitantactivationofcryptic Splice site coordinates are mapped against the NCBI36/hg18 human genome assembly. Strittmatter, PD Dr. Günter (G.St.) the normal 5' splice site, a cryptic 5' splice site can be activated by increasing its complementarity to U1 snRNA. Campbell Biologie (Pearson Studium - Biologie), Verlag: Pearson Studium ein Imprint von Pearson Deutschland. Kaspar, Dr. Robert In more detail, coordinates of the splice sites from adjacent exon–intron–exon sequences are pooled into four-tuples which are then loaded into a relational database alongside the data linking them to their alignments. For constitutively spliced genes, these minor deletion endpoints occur very infrequently and are therefore candidate css. Each EST is aligned against the genome independently from other ESTs. and activated cryptic donor splice site do not differ, the competition in the patient between the two sites for members of the splicing machinery is in favor of the cryptic donor splice site. Tewes, Prof. Dr. Uwe Schindler, Dr. Franz (F.S.) Leven, Prof. Franz-Josef (F.J.L.)

By increasing the cutoff level of these matrices you may prevent false splice sites to be detected as putative alternative isoform or cryptic sites. [wxyz], Anhäuser, Marcus (M.A.) Download asset Open asset. Lay, Dr. Martin (M.L.) Eukaryotic genomes contain large numbers of splice sites, known as cryptic splice sites (css), which are generally held to be disadvantageous sites that are dormant or used only at low levels unless activated by mutation of nearby authentic or advantageous splice sites (1,2). Sauer, Prof. Dr. Peter (P.S.) Theopold, Dr. Ulrich (U.T.) Panesar, Arne Raj Klaus (K.G.) The reason why such css predictions turn out to be accurate (see below) is because of the restriction that the predicted css is paired with a commonly used splice site. Meier, Kirstin (K.M.) Braun, Andreas (A.Br.) Once activated, css may be used extremely efficiently, resulting in a wide range of genetic disease (3–5). Sander, Prof. Dr. Klaus (K.S.) Das Medikament Diclofenac tötete Millionen Geier in Südasien. Are splicing mutations the most frequent cause of hereditary disease? Reiner, Dr. Susann Annette (S.R.) Ssymank, Dr. Axel (A.S.) Mosbrugger, Prof. Dr. Volker (V.M.) Geparden nutzen Hotspots, um Informationen auszutauschen. Wegener, Dr. Dorothee (D.W.) Cassada, Dr. Randall (R.C.) We found that about 25% of the css within the coding sequence of the large family of genes that encode ribosomal proteins exactly match the position of introns that are present in equivalent genes from other species (Figure 4 and Supplementary Figure S4). Starck, PD Dr. Matthias (M.St.) Of the five new css identified by CSF, three exactly match the position of introns in other species, therefore extending our previous study and adding further support to the validity of CSF predictions (Supplementary Figure S2). This result together with the clear consensus sequence results shown in Table 1 indicates that CSF predictions are highly reliable and can only generate a very low level of false positives even when supported by single ESTs. Hoos, Katrin (K.H.) [jkl] CSF defines the common deletion endpoints as authentic splice sites and the less common deletion endpoint of the minor transcript(s) as cryptic or alternative splice sites (arrowed). Lützenkirchen, Dr. Günter (G.L.) B. zu defekten Hämoglobinen bei manchen Thalassämien . Activation of a cryptic splice-site in intron 24 leads to the formation of apolipoprotein B-27.6. Duffner, Dr. Klaus (K.D.) As illustrated in Figure 1A, css can be 5′ or 3′ and upstream or downstream of the alternative authentic splice site. Körner, Dr. Helge (H.Kör.) The circle identifies a pattern of alignments that is recognized by CSF because it includes a minor transcript that has an unusual deletion endpoint (position 5 204 752) that is a predicted css (Figures 1B and 2A).
