WebDec 20, 2024 · These cryptic splicing events are inclusion of a cryptic exon embedded deep within an intron; selection of cryptic 5ʹ and 3ʹ splice sites; and aberrant recognition of cryptic splice sites within an exon, leading to the interior of this exon being aberrantly recognized as an intron (in a cryptic splicing event known as an exitron). WebThe spliceosome is capable of “reading” specific conserved sequence types to identify the exon-intron boundaries that can be distinctly recognized as (a) the 5′ splice site (5′SS) that ends in a GU dinucleotide at the intron end, (b) 3′ splice site (3′SS), (c) the polypyrimidine tract located upstream of the 3′SS ending with AG dinucleotide, and (d) the branch site …
