  1. ...constructs also incorporated longer flanking intronic sequences, enabling capture of additional splicing signals that could influence splice site recognition.The SeqSplice method was sensitive to detect splice-altering variants irrespective of the produced specific aberrant transcript. Therefore, SeqSplice...
  2. ...are either not regulated or cleared in vivo (Fig. 3C; Supplemental Fig. S3A). The widespread clearance supports the existence of proofreading mechanisms that suppress the recognition of cryptic sites to ensure accurate splicing. In addition, we observe a substantial number of stabilized U2AF2 binding sites...
  3. ...AG|r (Fig. 1B), which matches the genomic consensus 39 splice site and intron|exon boundary that crosslinks with U2AF1 (Wu et al. 1999). Nevertheless, our understanding of U2AF1:RNA interactions is incomplete. U2AF1’s U2AF homologymotif (UHM) is known tomediate U2AF1: U2AF2 heterodimer formation (Kielkopf...
  4. ...found that G. lamblia assemblage A does not use any known auxiliary element (Bilodeau et al. 2022), highlighting the potential diversity of cleavage site recognition within the eukaryotic tree.View larger version: In this window In a new window Figure 1. Characterization of poly(A) signals in diverse...
  5. ...of (AC)m-(GT)n intron splicing in vivo, morpholino oligo injection was used to block the translation of U2AF2 paralogs in zebrafish embryos. Zebrafish carries two U2af2 homologs, U2af2a and U2af2b. These paralogs share 88% sequence identity; they both encode three RNA-recognition motifs (RRMs), a U2AF...
  6. ...aberrant HIV-1-to-host RNA splicing as 13 seen in vivo (Liu et al. 2020). Using four cell line clones as biological replicates enables us to interrogate how 14 different HIV-1 integration sites impact HIV-1-host chromatin interactions. 15 16 17 HIV-1 proviral chromatin accessibility correlates with host...

  7. ...clinical disease manifestation in Fanconi Anemia C patients (Hartmann et al. 2010), underlining the clinical importance of noncanonical splice site recognition.Extensive sequence complementarity between splice junctions in hnRNA molecules and the nucleotide sequence at the 5′ end of U1 snRNA was already...
  8. ...of a strong RHO splice donor and acceptor site, as we observed erroneous exon skipping in MG_ex40 (Fig. 1).Natural skipping of ABCA4 exons 3, 15, and 39/40 was observed by others (Braun et al. 2013) and by us (Supplemental Fig. S2), suggesting that the midigenes mimic the in vivo situation. An accurate...
  9. ...of the preferred nucleotide at one half-site of tDNA can increase the chances of the less preferred nucleotide appearing at the other half-site of tDNA. We thus consider the model in which triggering the strand transfer reaction after tDNA recognition by IN can act asymmetrically.In vitro experiments suggested...
  10. ...databases might be relatively benign owing to the availability of a suitable backup splice site, and thus not additionally punished by the presence of a second mutation.One of the first steps of the splicing process is the recognition of 5′ss by U1 snRNP, which is one of the five snRNPs making up...
