>cd05113 PTKc_Btk_Bmx Catalytic Domain of the Protein Tyrosine Kinases, Bruton's tyrosine kinase and Bone marrow kinase on the X chromosome. Protein Tyrosine Kinase (PTK) family; Bruton's tyrosine kinase (Btk) and Bone marrow kinase on the X chromosome (Bmx); 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. Btk and Bmx (also named Etk) are members of the Tec subfamily of proteins, which are cytoplasmic (or nonreceptor) tyr kinases 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
