Entrez Gene Number
Entrez Gene SummaryThis gene encodes a serine/arginine protein kinase specific for the SR (serine/arginine-rich domain) family of splicing factors. The protein localizes to the nucleus and the cytoplasm. It is thought to play a role in regulation of both constitutive and alternative splicing by regulating intracellular localization of splicing factors. A second alternatively spliced transcript variant for this gene has been described, but its full length nature has not been determined.
Gene Symbol
  • SRPK1
  • SFRSK1
Protein TargetSRPK1
Purification MethodGlutathione-agarose
Target Sub-FamilyCMGC
UniProt Number
UniProt SummaryFUNCTION: SwissProt: Q96SB4 # Plays a central role in the regulatory network for splicing, controlling the intranuclear distribution of splicing factors in interphase cells and the reorganization of nuclear speckles during mitosis. Hyperphosphorylates RS domain-containing proteins such as SFRS1 and SFRS2 on serine residues during metaphase but at lower levels during interphase. Locks onto SFRS1 to form a stable complex and processively phosphorylates the RS domain. Appears to mediate HBV core protein phosphorylation which is a prerequisite for pregenomic RNA encapsidation into viral capsids.
COFACTOR: Magnesium.
SIZE: 826 amino acids; 92407 Da
SUBUNIT: Present in a seven component complex, the toposome, which separates entangled circular chromatin DNA during chromosome segregation. The extended N-terminal domain of isoform 1 binds to the nuclear scaffold-associated protein SAFB suggesting this isoform may phosphorylate splicing factors in close vicinity to the nuclear matrix.
SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Isoform 1 and isoform 2 are cytoplasmic and nuclear.TISSUE SPECIFICITY: Isoform 2 is predominantly expressed in the testis but is also present at lower levels in heart, ovary, small intestine, liver, kidney, pancreas and skeletal muscle. Isoform 1 is only seen in the testis, at lower levels than isoform 2.
SIMILARITY: SwissProt: Q96SB4 ## Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. & Contains 1 protein kinase domain.
