Csk Monoclonal Antibody

Catalytic activity:ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate., function:Specifically phosphorylates 'Tyr-504' on LCK, which acts as a negative regulatory site. Can also act on the LYN and FYN kinases., PTM:Autophosphorylation of Tyr-304 occurs only at abnormally high CSK concentrations in vitro., similarity:Belongs to the protein kinase superfamily. Tyr protein kinase family., similarity:Belongs to the protein kinase superfamily. Tyr protein kinase family. CSK subfamily., similarity:Contains 1 protein kinase domain., similarity:Contains 1 SH2 domain., similarity:Contains 1 SH3 domain., subcellular location:Mainly cytoplasmic, also present in lipid rafts., subunit:Interacts with PTPN8 (By similarity) . Interacts with phosphorylated SIT1, PAG1, LIME1 and TGFB1I1., tissue specificity:Expressed in lung and macrophages.
