- C SRC
- C SRC kinase
- C src Tyrosine Kinase
FunctionSpecifically phosphorylates 'Tyr-504' on LCK, which acts as a negative regulatory site. Can also act on the LYN and FYN kinases.
Tissue specificityExpressed in lung and macrophages.
Sequence similaritiesBelongs to the protein kinase superfamily. Tyr protein kinase family. CSK subfamily.
Contains 1 protein kinase domain.
Contains 1 SH2 domain.
Contains 1 SH3 domain.
modificationsAutophosphorylation of Tyr-304 occurs only at abnormally high CSK concentrations in vitro.
Cellular localizationCytoplasm. Cell membrane. Mainly cytoplasmic, also present in lipid rafts.
