Protein function

Non-receptor tyrosine-protein kinase that plays an important role in the regulation of cell growth, differentiation, migration and immune response. Phosphorylates tyrosine residues located in the C-terminal tails of Src-family kinases (SFKs) including LCK, SRC, HCK, FYN, LYN or YES1. Upon tail phosphorylation, Src-family members engage in intramolecular interactions between the phosphotyrosine tail and the SH2 domain that result in an inactive conformation. To inhibit SFKs, CSK is recruited to the plasma membrane via binding to transmembrane proteins or adapter proteins located near the plasma membrane. Suppresses signaling by various surface receptors, including T-cell receptor (TCR) and B-cell receptor (BCR) by phosphorylating and maintaining inactive several positive effectors such as FYN or LCK. / ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. / Mg2+

Protein tissue specificity

Expressed in lung and macrophages.

Protein sequence and domain

The architecture of this protein is similar to that of Src-family kinases (SFKs) with one N-terminal SH3 domain, one SH2 domain, and a C-terminal kinase domain. / Belongs to the protein kinase superfamily. Tyr protein kinase family. CSK subfamily. / Contains 1 protein kinase domain. / Contains 1 SH2 domain. / Contains 1 SH3 domain.

Protein post-translational modifications

Phosphorylated at Ser-364 by PKA, leading to increased activity. Autophosphorylated.
