Background

SRPK3 (Ser/Arg-rich protein specific kinase 3), also called MSSK-1 (muscle-specific serine kinase 1) or STK23 (Ser/Thr kinase 23) is a 59 kDa (predicted) cytoplasmic member of the CMGC Ser/Thr protein kinase family. SRPK3 is principally expressed in heart and skeletal muscle. SRPKs selectively phosphorylate Ser on RS domain-containing proteins, initiating mRNA splicing and maturation.  The 533 amino acid (aa) human SRPK3 contains a split kinase domain (aa 79‑292 and 347‑531) separated by a hinge region. A 491 aa isoform shows an alternate translation start site at aa 43. Within the region used as an immunogen, human SRPK3 shares 87% and 86% aa identity with mouse and rat SRPK3, respectively.
