Function
Hck, a member of the Src family non-receptor tyrosine kinases, functions as a critical regulator of intracellular signaling, modulating protein tyrosine phosphorylation and downstream effector activation[1][2]. Mechanistically, Hck participates in immune cell migration and monocyte chemotaxis through Src-MAPK and ERK1/2 signaling pathways, integrating extracellular adhesion cues into cytoskeletal reorganization[2]. In disease models, Hck activity contributes to inflammatory processes in rheumatoid arthritis and atherosclerosis, and is implicated in malignancies through dysregulated Src family kinase signaling[1][2]. Compared with related isoforms, such as Src and Lyn, Hck exhibits selective expression in hematopoietic lineages and unique responsiveness to chemotactic and adhesion stimuli, enabling differential regulation of monocyte versus general leukocyte signaling[3][2]. Pharmacologically, small-molecule inhibitors targeting Hck’s inactive conformation demonstrate selective suppression of Hck-mediated signaling without affecting closely related kinases, providing tools for dissecting its role in immune and cancer models[1]. These inhibitors exploit structural features of Hck to reduce promiscuity and cytotoxicity, supporting their application in both experimental and potential therapeutic contexts[1]. Collectively, these findings establish Hck as a functionally distinct kinase within the Src family, mediating critical signaling in immunity and disease, and amenable to isoform-specific pharmacological intervention[1][2].

Isoforms & Post-Translational Modification
P08631 has 4 isomers: P08631-1: 59600 Da (predicted); P08631-2: 57312 Da (predicted); P08631-3: 57241 Da (predicted); P08631-4: 59529 Da (predicted).
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 -
Subunit
Interacts (via SH2 domain) with FLT3 (tyrosine phosphorylated). Interacts with VAV1, WAS and RAPGEF1 (By similarity). 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
