>cd05112 PTKc_Itk Catalytic Domain of the Protein Tyrosine Kinase, Interleukin-2-inducible T-cell Kinase. Protein Tyrosine Kinase (PTK) family; Interleukin-2 (IL-2)-inducible T-cell kinase (Itk); 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. Itk (also known as Tsk or Emt) is a member 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 the products of PI3K and allows membrane recruitment and activ
