text: The Suppressor-of-White-APricot domain regulates this process.
full_question: The Suppressor-of-White-APricot domain regulates this process. Prp24 helps form a duplex during thisprocess, which is promoted by serine/arginine-rich SR proteins binding to ESEs. Parts for this process arestored in namesake speckles. This process starts with an attack on a namesake donor site by the branchpoint,which then attacks the 3-prime acceptor site adjacent to a polypyrimidine tract in a second transesterification.Its "alternative" type produces protein isoforms. U4, U5, and U6 snRNAs form a triple-snurp complex during it.The reading frame can be restored in this process by skipping over exons. For 10 points, name this process inwhich introns are excised from pre-mRNA.
