Background: SRPK2

SRPK2 (Ser/Arg-rich protein specific kinase 2) is a cytoplasmic, 115‑120 kDa member of the CMGC Ser/Thr protein kinase family of enzymes. It is expressed in many experimental cell lines and serves to selectively phosphorylate Ser on RS domain-containing proteins. This phosphorylation activates RS domain-containing non-snRNP proteins in the spliceosome complex, and initiates mRNA splicing. Human SRPK2 is 688 amino acids (aa) in length. It contains a Pro-rich region (aa 21‑45) that may interact with WW domain-containing proteins, and a split kinase domain (aa 79‑226 and 524‑646). Phosphorylation on S52 and S588 regulates activity. There are at least two splice variants. One shows a 24 aa substitution for aa 1‑13, while a second shows a nine aa substitution for aa 538‑688.
