ITK（IL2 inducible T cell kinase），癌症关联基因，基因ID：3702，该基因编码在t细胞中表达的细胞内酪氨酸激酶。该蛋白包含sh2和sh3两个结构域，它们通常存在于细胞内激酶中。它被认为在t细胞增殖和分化中起作用。[由RefSeq提供，2008年7月]This gene encodes an intracellular tyrosine kinase expressed in T-cells. The protein contains both SH2 and SH3 domains which are often found in intracellular kinases. It is thought to play a role in T-cell proliferation and differentiation. [provided by RefSeq， Jul 2008]。
