PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	one SH3 and SH2 domains, playing important roles in substrate targeting, noncatalytic regions working together as a "conformational switch" that modulates kinase activity in a manner unique to the SH3 domain and linker topologies present in the intact HCK protein
	a bipartite kinase domain

HOMOLOGY

interspecies	homolog to rattus Hck (89.89 pc)
	homolog to murine Hck (90.08 pc)

Homologene

FAMILY	protein kinase superfamily
	Tyr protein kinase family
	Src-family kinases

CATEGORY

enzyme , protooncogene

SUBCELLULAR LOCALIZATION

plasma membrane

basic FUNCTION	contributing to neutrophil migration and regulating the degranulation process of neutrophils
	EIF2AK2 and HCK were critical for DON-induced ribosomal recruitment of MAPK14, its subsequent phosphorylation, and, ultimately, MAPK14-driven proinflammatory cytokine expression
	acts as a key regulator controlling gene expression in alternatively activated monocytes/macrophages
	major signaling kinase in alternatively activated monocytes/macrophages by IL13, implicating a central role for SRC family kinases in atherogenesis and chronic inflammation
	critical for regulating alternative activation of monocytes/macrophages

INTERACTION

DNA

RNA

small molecule	nucleotide,
	ATP

protein	interacting with ADAM15 (regulates leukocyte function)
	interacting with RAPGEF1, to activate kinase-dependent and caspase-mediated apoptosis, which is independent of catalytic domain of C3G
	recruited by integrin alpha(M)beta(2)
	interacting with TP73 (HCK-SH3 domain-mediated interactions play an important role in the inhibition of TP73-dependent transcriptional activation of a target gene, NLRC4, as well as apoptosis)
	interacting with CSF1R (dysregulated activation of HCK at the Golgi disturbs N-glycosylation of a cytokine receptor CSF1R)
	PDCD6IP is a novel HCK (haemopoietic cell kinase) SH3 domain interactor
	regulates the expression of mannose receptor, CD36, and MAOA in alternatively activated monocytes by IL13
	C-terminal 40 amino acids of HCK selectively bound to NLRP12 PYD + NBD
