ITK is a T cell signaling protein. The Tec family of non receptor tyrosine kinases is composed of six proteins designated Tec, ITK (also known as Emt or Tsk), Btk (previously known as Atk, BPK or Emb), Bmx, Txk (also known as Rlk) and Dsrc28C. All members of the family contain SH3 and SH2 domains and, with the exception of Txk and Dsrc28C, also contain pleckstrin homology (PH) and Tec homology (TH) domains in their amino termini. ITK associates with CD28 and becomes activated subsequent to CD28 ligation.
