Protein Information
Name ITK
Synonyms EMT, LYK
Function Tyrosine kinase that plays an essential role in regulation of the adaptive immune response. Regulates the development, function and differentiation of conventional T-cells and nonconventional NKT-cells. When antigen presenting cells (APC) activate T-cell receptor (TCR), a series of phosphorylation lead to the recruitment of ITK to the cell membrane, in the vicinity of the stimulated TCR receptor, where it is phosphorylated by LCK. Phosphorylation leads to ITK autophosphorylation and full activation. Once activated, phosphorylates PLCG1, leading to the activation of this lipase and subsequent cleavage of its substrates. In turn, the endoplasmic reticulum releases calcium in the cytoplasm and the nuclear activator of activated T-cells (NFAT) translocates into the nucleus to perform its transcriptional duty. Phosphorylates 2 essential adapter proteins: the linker for activation of T-cells/LAT protein and LCP2. Then, a large number of signaling molecules such as VAV1 are recruited and ultimately lead to lymphokine production, T-cell proliferation and differentiation.
Cellular Location Cytoplasm. Note=Localizes in the vicinity of cell surface receptors in the plasma membrane after receptor stimulation
Tissue Location T-cell lines and natural killer cell lines.

Background

Emtk/Itk/Tsk is a member of the Tec family of Protein Tyrosine Kinase (PTK) expressed in T, NK, and mast cells (1). Structurally, Emtk/Itk/Tsk possesses a tyrosine kinase (TK), a pleckstrin homology (PH) and a TEC homology domain. It also contains both SRC homology 2 (SH2) and a SRC homology 3 (SH3) domains (2). It lacks as well the amino-terminal myristylation signal and the negative autoregulatory phosphorylation site present in all members of the Src family of PTKs (3). Additionally, the Src tyrosine kinase LCK is required for Emtk/Itk/Tsk activation and recruitment by CD28 (4).
