>cd05073 PTKc_Hck Catalytic Domain of the Protein Tyrosine Kinase, Hematopoietic cell kinase. Protein Tyrosine Kinase (PTK) family; Hematopoietic cell kinase (Hck); catalytic (c) domain. The PTKc family is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, and phosphoinositide 3-kinase (PI3K). PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Hck is a member of the Src subfamily of proteins, which are cytoplasmic (or non-receptor) tyr kinases. Src kinases contain an N-terminal SH4 domain with a myristoylation site, followed by SH3 and SH2 domains, a tyr kinase domain, and a regulatory C-terminal region containing a conserved tyr. They are activated by autophosphorylation at the tyr kinase domain, but are negatively regulated by phosphorylation at the C-terminal tyr by Csk (C-terminal Src Kinase). Src proteins are involved in signaling pa
