This gene encodes a member of the arginine/serine-rich splicing factor protein family. The encoded protein can either activate or repress splicing, depending on its phosphorylation state and its interaction partners. Multiple transcript variants have been found for this gene. There is a pseudogene of this gene on chromosome 13. [provided by RefSeq, Jun 2014]

Among its related pathways are mRNA Splicing - Major Pathway and Influenza A. GO annotations related to this gene include nucleic acid binding and RNA binding. An important paralog of this gene is SRSF9.
UniProtKB/Swiss-Prot for SRSF1 Gene
Plays a role in preventing exon skipping, ensuring the accuracy of splicing and regulating alternative splicing. Interacts with other spliceosomal components, via the RS domains, to form a bridge between the 5- and 3-splice site binding components, U1 snRNP and U2AF. Can stimulate binding of U1 snRNP to a 5-splice site-containing pre-mRNA. Binds to purine-rich RNA sequences, either the octamer, 5-RGAAGAAC-3 (r=A or G) or the decamers, AGGACAGAGC/AGGACGAAGC. Binds preferentially to the 5-CGAGGCG-3 motif in vitro. Three copies of the octamer constitute a powerful splicing enhancer in vitro, the ASF/SF2 splicing enhancer (ASE) which can specifically activate ASE-dependent splicing. Isoform ASF-2 and isoform ASF-3 act as splicing repressors. May function as export adapter involved in mRNA nuclear export through the TAP/NXF1 pathway.
