Summary

HCK (HCK proto-oncogene, Src family tyrosine kinase, HGNC:4840) is a protein-coding gene on chromosome 20q11.21, encoding Tyrosine-protein kinase HCK (P08631). 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 s….

The protein encoded by this gene is a member of the Src family of tyrosine kinases. This protein is primarily hemopoietic, particularly in cells of the myeloid and B-lymphoid lineages. It may help couple the Fc receptor to the activation of the respiratory burst. In addition, it may play a role in neutrophil migration and in the degranulation of neutrophils. Multiple isoforms with different subcellular distributions are produced due to both alternative splicing and the use of alternative translation initiation codons, including a non-AUG (CUG) codon.

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.

Subunit / interactions. Interacts (via SH2 domain) with FLT3 (tyrosine phosphorylated). Interacts with VAV1, WAS and RAPGEF1. This interaction stimulates its tyrosine-kinase activity. Interacts with ARRB1 and ARRB2. Interacts with ADAM15. Interacts with FASLG. Interacts with CBL. Interacts with FCGR1A; the interaction may be indirect. Interacts with IL6ST. Interacts (via SH3 domain) with ELMO1. Interacts (via SH3 domain) with TP73. Interacts with YAP1. Interacts with ABL1 and ITGB1, and thereby recruits ABL1 to activated ITGB1. Interacts (via SH3 domain) with WDCP. (Microbial infection) Interacts (via SH3 domain) with HEV ORF3 protein. (Microbial infection) Interacts (via SH3 domain) with HIV-1 Nef and Vif.

Subcellular location. Lysosome. Membrane. Cell projection. Podosome membrane. Cytoplasm. Cytosol Cell membrane. Caveola. Cell junction. Focal adhesion. Cytoskeleton. Golgi apparatus. Cytoplasmic vesicle. Nucleus Cytoplasmic vesicle. Secretory vesicle. Cytosol.

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.

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.

Disease relevance. Aberrant activation of HCK by HIV-1 protein Nef enhances HIV-1 replication and contributes to HIV-1 pathogenicity. Aberrant activation of HCK, e.g. by the BCR-ABL fusion protein, promotes cancer cell proliferation. Autoinflammation with pulmonary and cutaneous vasculitis (AIPCV) [MIM:620296] An autosomal dominant disorder characterized by cutaneous vasculitis and chronic pulmonary inflammation that evolves to fibrosis. AIPCV manifests soon after birth with petechial skin lesions, followed by progressive pulmonary involvement causing restrictive lung disease and respiratory insufficiency. The disease may be caused by variants affecting the gene represented in this entry.

Activity regulation. 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.

Domain organisation. The SH3 domain mediates binding to HIV-1 Nef.

Induction. Up-regulated during myeloid cell differentiation. The highest levels are detected in fully differentiated phagocytes. Up-regulated by IL2.

Miscellaneous. Initiates from a CTG codon. Initiates from a CTG codon.

Similarity. Belongs to the protein kinase superfamily. Tyr protein kinase family. SRC subfamily.

Reactome pathways and GO biological processes over-represented among this gene’s 66 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.

Drugs by curated mechanism of action (ChEMBL)

Drugs whose curated ChEMBL mechanism of action targets the HCK protein itself — single-protein targets only (drugs acting on a protein family or complex that merely includes it are excluded). Includes antibodies and oligonucleotides that bioactivity screening does not capture.

Drugs acting on a complex or family that includes this protein

Curated ChEMBL mechanism-of-action drugs whose target is a protein complex or family of ≤10 members that includes HCK — the drug acts on the assembly or class, not necessarily on this subunit alone.
