WebSep 1, 2024 · Cryptic splice site Splicing occurs at the 5′ and 3′ ends of intronic regions of the precursor messenger RNA s (pre-mRNA), which are known as 5′ and 3′ splice sites. The splicing is promoted by a spliceosome complex which recognizes the exon-intron boundaries and removes the intron with single nucleotide precision. WebA cryptic splice site is a mRNA sequence that has the potential for interacting with the spliceosome. Mutations, including splice site mutations, in the underlying DNA or errors during transcription can activate a cryptic splice … Due to the sensitive location of splice sites, mutations in the acceptor or donor areas of splice sites can become detrimental to a human individual.
