Description_x000D_ General description_x000D_ ITK (IL2-inducible T-cell kinase) is a member of the Tec family of tyrosine kinases. ITK is expressed in T-cells._x000D_ Biochem/physiol Actions_x000D_ ITK (IL2-inducible T-cell kinase) is important for T-cell activation through the T-cell antigen receptor. Absence of ITK in T cells causes impairment in TCR (T cell receptor)-mediated actin polymerization, cell polarization and signaling events associated with cytoskeletal reorganization._x000D_ Physical form_x000D_ Supplied in 50 mM Tris-HCl, pH 7.5, with 150 mM NaCl, 0.2 5mM DTT, 0.1 mM EGTA, 0.1 mM EDTA, 0.1 mM PMSF, and 25% glycerol._x000D_ Legal Information_x000D_ PRECISIO is a registered trademark of Sigma-Aldrich Co.
