Abstract
SF2 is a protein factor essential for constitutive pre-mRNA splicing in HeLa cell extracts and also activates proximal alternative 5' splice sites in a concentration-dependent manner. This latter property suggests a role for SF2 in preventing exon skipping, ensuring the accuracy of splicing, and regulating alternative splicing. Human SF2 cDNAs have been isolated and overexpressed in bacteria. Recombinant SF2 is active in splicing and stimulates proximal 5' splice sites. SF2 has a C-terminal region rich in arginine-serine dipeptides, similar to the RS domains of the U1 snRNP 70K polypeptide and the Drosophila alternative splicing regulators transformer, transformer-2, and suppressor-of-white-apricot. Like transformer-2 and 70K, SF2 contains an RNP-type RNA recognition motif.
