  • 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.
  • Post-translational
    modifications
    Autophosphorylation of Tyr-304 occurs only at abnormally high CSK concentrations in vitro.
  • Cellular localizationCytoplasm. Cell membrane. Mainly cytoplasmic, also present in lipid rafts.
  • Information by UniProt
