Protein function

Non-receptor tyrosine-protein kinase found in hematopoietic cells that transmits signals from cell surface receptors and plays an important role in the regulation of innate immune responses, including neutrophil, monocyte, macrophage and mast cell functions, phagocytosis, cell survival and proliferation, cell adhesion and migration. Acts downstream of receptors that bind the Fc region of immunoglobulins, such as FCGR1A and FCGR2A, but also CSF3R, PLAUR, the receptors for IFNG, IL2, IL6 and IL8, and integrins, such as ITGB1 and ITGB2. During the phagocytic process, mediates mobilization of secretory lysosomes, degranulation, and activation of NADPH oxidase to bring about the respiratory burst. Plays a role in the release of inflammatory molecules. Promotes reorganization of the actin cytoskeleton and actin polymerization, formation of podosomes and cell protrusions. Inhibits TP73-mediated transcription activation and TP73-mediated apoptosis. Phosphorylates CBL in response to activation of immunoglobulin gamma Fc region receptors. Phosphorylates ADAM15, BCR, ELMO1, FCGR2A, GAB1, GAB2, RAPGEF1, STAT5B, TP73, VAV1 and WAS. / ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. / Subject to autoinhibition, mediated by intramolecular interactions involving the SH2 and SH3 domains. Kinase activity is also regulated by phosphorylation at regulatory tyrosine residues. Phosphorylation at Tyr-411 is required for optimal activity. Phosphorylation at Tyr-522 inhibits kinase activity. Inhibited by PP1 and A-770041.

Protein tissue specificity

Detected in monocytes and neutrophils (at protein level). Expressed predominantly in cells of the myeloid and B-lymphoid lineages. Highly expressed in granulocytes. Detected in tonsil.

Involvement in disease

Note: Aberrant activation of HCK by HIV-1 protein Nef enhances HIV-1 replication and contributes to HIV-1 pathogenicity.; Note: Aberrant activation of HCK, e.g. by the BCR-ABL fusion protein, promotes cancer cell proliferation.

Protein sequence and domain

The SH3 domain mediates binding to HIV-1 Nef. / Belongs to the protein kinase superfamily. Tyr protein kinase family. SRC subfamily. / Contains 1 protein kinase domain. / Contains 1 SH2 domain. / Contains 1 SH3 domain.

Protein post-translational modifications

Phosphorylated on several tyrosine residues. Autophosphorylated. Becomes rapidly phosphorylated upon activation of the immunoglobulin receptors FCGR1A and FCGR2A. Phosphorylation by the BCR-ABL fusion protein mediates activation of HCK. Phosphorylation at Tyr-411 increases kinase activity. Phosphorylation at Tyr-522 inhibits kinase activity. Kinase activity is not required for phosphorylation at Tyr-522, suggesting that this site is a target of other kinases. / Ubiquitinated by CBL, leading to its degradation via the proteasome. / Isoform 2 palmitoylation at position 2 requires prior myristoylation. Palmitoylation at position 3 is required for caveolar localization of isoform 2.
