Background: CSK also known as C-Src kinase or C-terminal Src kinase is a non-receptor tyrosine-protein kinase that plays an important role in the regulation of cell growth, differentiation, migration and immune response. CSK is able to suppresses activity of the Src family of protein kinases (SFKs) by phosphorylation of tyrosine residues located in the C-terminal tails of SFKs including LCK, SRC, HCK, FYN, LYN or YES1.

Human CSK (C-Src kinase) tyrosine kinase, full length, amino acids M1-L450 (as in NCBI/Protein entry NP_004374.1), recombinant and active enzyme, N-terminal GST-HIS6 fusion protein with a Thrombin cleavage site
