Identification
HMDB Protein ID CDBP01353
Secondary Accession Numbers Not Available
Name Tyrosine-protein kinase SYK
Description Not Available
Synonyms
  1. Spleen tyrosine kinase
Gene Name SYK
Protein Type Enzyme
Biological Properties
General Function Involved in protein kinase activity
Specific Function Positive effector of BCR-stimulated responses. Couples the B-cell antigen receptor (BCR) to the mobilization of calcium ion either through a phosphoinositide 3-kinase-dependent pathway, when not phosphorylated on tyrosines of the linker region, or through a phospholipase C-gamma-dependent pathway, when phosphorylated on Tyr-348 and Tyr-352. Thus the differential phosphorylation of Syk can determine the pathway by which BCR is coupled to the regulation of intracellular calcium ion. Phosphorylates USP25 and regulates its intracellular levels
