Serine/arginine-rich splicing factor 1 (SFRS1) also known as alternative splicing factor 1 (ASF1) pre-mRNA-splicing factor SF2 (SF2) or ASF1/SF2 is a protein that in humans is encoded by the SFRS1 gene. ASF/SF2 is an essential sequence specific splicing factor involved in pre-mRNA splicing. SFRS1 is the gene that codes for ASF/SF2 and is found on chromosome 17. The resulting splicing factor is a protein of approximately 33 kDa.
