SRSF protein kinase family
srsf protein kinase family
SRSF protein kinases (SPRKs) constitute a subfamily of CMGC serine-threonine kinases that specifically phosphorylate serine residues within regions that are rich in serine-arginine dipeptide motifs, also called SR domains. The serine-arginine splicing factors (SRSFs) are the primary substrates for the SRPKs.
