>cd05052 PTKc_Abl Catalytic Domain of the Protein Tyrosine Kinase, Abelson kinase. Protein Tyrosine Kinase (PTK) family; Abelson (Abl) kinase; 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. Abl (or c-Abl) is a ubiquitously-expressed cytoplasmic (or nonreceptor) tyr kinase that contains SH3, SH2, and tyr kinase domains in its N-terminal region, as well as nuclear localization motifs, a putative DNA-binding domain, and F- and G-actin binding domains in its C-terminal tail. It also contains a short autoinhibitory cap region in its N-terminus. Abl is normally inactive and requires phosphorylation and myristoylation for activation. Abl function depends on its subcellular localization. In the cytoplasm, Abl plays
