Background Information

SRPK2, also named as serine/arginine protein kinase 2 and SFRSK2, belongs to SR protein-specific kinase family which phosphorylate the serine/arginine domain containing proteins in the nuclear speckles to mediate pre-mRNA splicing (PMID: 22854045). In addition to its major role as kinase for the phosphorylation of SR proteins, SRPK2 is involved in cell cycle regulation and cell apoptosis (PMID: 19592491). SRPK2 promotes the proliferation and migration of the colon cancer cells. It has been reported to be regulated in several cancer types (PMID: 27041240). It has 2 isoforms with the calculated molecular mass of 77-79 kDa, and the apparent molecular mass of 105-115 kDa due to posttranslational modification (PMID: 12134018, 16122776).
