SF2 also known as Splicing Factor 2 or Alternative Splicing Factor 1 (ASF1) is a prototypical member of the SR protein family involved in mRNA splicing. It is approximately 33 kDa in mass. SF2 is expressed ubiquitously in the nucleus of eukaryotic cells where it plays a central role in the regulation of constitutive and alternative splicing processes.
Biological function summary
SF2 acts as an important regulator of gene expression by facilitating the splicing of pre-mRNA participating in spliceosome assembly. It interacts with other splicing factors and RNA to form spliceosomal complexes essential for splicing fidelity and efficiency. The precise modulation of splicing by SF2 allows for the generation of diverse protein isoforms from a single gene contributing to protein diversity within the cell.
Pathways
SF2 integrates into the RNA splicing pathway and is critical for splice site selection. It interacts with proteins such as U1 snRNP and U2AF65 influencing their binding to pre-mRNA. SF2 also plays roles in other key pathways like mRNA transport and translation thereby linking the splicing machinery with nuclear export and protein synthesis processes.
Abnormalities in SF2 levels or functions have been linked to various cancers and spinal muscular atrophy (SMA). Cancer cells often show altered SF2 expression leading to splicing anomalies that promote tumorigenesis. Additionally SF2's interaction with proteins like hnRNP A1 influences disease mechanisms as splicing factor dysregulation can disrupt normal cellular processes and facilitate the progression of disorders such as SMA.
