WebDec 7, 2024 · The splice donor site includes an almost invariant sequence GU at the 5' end of the intron, within a larger, less highly conserved region. The splice acceptor site at the 3' end of the intron terminates the intron with an almost invariant AG sequence. WebApr 24, 2024 · Splicing is a key process in eukaryotic cells. After transcription, a nascent pre-mRNA must be converted into a mature mRNA that can serve as a template for protein translation. This involves the removal of introns from the pre-mRNA, usually by the major spliceosome, through splicing (Fig. 1 a).

WebMar 15, 2024 · RNA splicing is a key process in biology where non-coding regions of RNA (introns) are removed and exons joined together, to generate the mature messenger RNA (mRNA) that will be translated (1). In eukaryotes, alternative splicing occurs in ∼95% of multi-exonic genes and generates a diversity of protein isoforms from a single gene (2). WebJul 20, 2024 · The cryptic splice site leads to the removal of 31 nucleotides from the transcript and thereby disrupts the function of MLH1. SQUIRLS was trained on a large dataset of non-canonical splice-affecting variants, and as such performs particularly well in identifying difficult-to-classify variants located outside the canonical sequences.
