>cd05040 PTKc_Ack_like Catalytic Domain of the Protein Tyrosine Kinase, Activated Cdc42-associated kinase. Protein Tyrosine Kinase (PTK) family; Activated Cdc42-associated kinase (Ack) subfamily; catalytic (c) domain. Ack subfamily members include Ack1, thirty-eight-negative kinase 1 (Tnk1), and similar proteins. 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. Ack subfamily members are cytoplasmic (or nonreceptor) tyr kinases containing an N-terminal catalytic domain, an SH3 domain, a Cdc42-binding CRIB domain, and a proline-rich region. They are mainly expressed in brain and skeletal tissues and are involved in the regulation of cell adhesion and growth, receptor degradation, and axonal guidance. Ack1 is also associated with and
