SRSF protein kinase 2, or, SRPK2, is a human gene. Other names include: Serine/arginine-rich protein-specific kinase 2; SR-protein-specific kinase 2; SFRS protein kinase 2; SRSF protein kinase 2 ; SR protein kinase 2; serine/arginine-rich splicing factor kinase 2; SFRSK2. The encoded protein is an enzyme with an amino acid length of 688 and a mass of 77.5 kDa. Other isoforms may exist. SRSF protein kinase 2 is a member of the Protein kinase superfamily, CMGC Ser/Thr protein kinase family. This gene shares homology with other species, including: Rat, Zebrafish, Frog, Chicken.
