>cd05059 PTKc_Tec_like Catalytic Domain of Tec-like Protein Tyrosine Kinases. Protein Tyrosine Kinase (PTK) family; Tyrosine kinase expressed in hepatocellular carcinoma (Tec) subfamily; catalytic (c) domain. The Tec subfamily is composed of Tec, Btk, Bmx (Etk), Itk (Tsk, Emt), Rlk (Txk), 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. Tec kinases are cytoplasmic (or nonreceptor) tyr kinases (nRTKs) with similarity to Src kinases in that they contain Src homology protein interaction domains (SH3, SH2) N-terminal to the catalytic tyr kinase domain. Unlike Src kinases, most Tec subfamily members (except Rlk) also contain an N-terminal pleckstrin homology (PH) domain, which binds the products of PI3K and allows
