Other Information

**Key Characteristics:** 1. **Tyrosine Kinase Activity:** ITK possesses non-membrane spanning protein tyrosine kinase activity, which allows it to phosphorylate and activate downstream signaling pathways. 2. **IL-2 Inducibility:** ITK is specifically induced by IL-2, a cytokine that promotes T cell proliferation, differentiation, and survival. 3. **T Cell Receptor Signaling:** ITK is required for the activation of T cells through the T cell receptor (TCR) signaling pathway, which is essential for the recognition of antigens and the initiation of an immune response. 4. **Cellular Localization:** ITK is primarily localized to the plasma membrane and cytosol, where it interacts with other signaling molecules to regulate T cell activation and function. **Pathways and Functions:** 1. **Activation of Phospholipase C Activity:** ITK phosphorylates and activates phospholipase C, which generates second messenger molecules such as diacylglycerol (DAG) and inositol trisphosphate (IP3). These molecules regulate various cellular processes, including calcium mobilization and cell proliferation. 2. **Adaptive Immune Response:** ITK is essential for the development and function of alpha-beta T cells, which are critical components of the adaptive immune system. ITK regulates T cell activation, proliferation, and differentiation, and is required for the production of cytokines and other immune molecules. 3. **Gamma-Delta T Cell Activation:** ITK is also required for the activation of gamma-delta T cells, which are a subset of T cells that recognize non-peptide antigens. 4. **NK Cell Differentiation:** ITK is involved in the differentiation and function of natural killer (NK) cells, which are a critical component of the innate immune system. **Clinical Significance:** 1. **Immunodeficiency Disorders:** Mutations in the ITK gene have been associated with immunodeficiency disorders, including severe combined immunodeficiency (SCID) and X-linked lymphoproliferative disease (XLP). 2. **Cancer:** ITK has been implicated in the development and progression of various cancers, including T cell lymphomas and leukemias. 3. **Autoimmune Diseases:** ITK has been shown to play a role in the development of autoimmune diseases, including rheumatoid arthritis and multiple sclerosis. 4. **Vaccine Development:** ITK has been identified as a potential target for the development of vaccines against infectious diseases, including HIV and tuberculosis. In conclusion, ITK is a critical regulator of T cell activation and immune response, and its dysregulation has been implicated in various immunodeficiency disorders, cancers, and autoimmune diseases. Further research on ITK is necessary to fully understand its role in the immune system and to develop effective therapeutic strategies for the treatment of immune-related diseases.

Database document:

This is a preview of the gene's schema. Only a few entries are kept for 'singleCellExpressions,' 'mRNAExpressions,' and other large data arrays for visualization purposes. You can zoom in with the mouse wheel for a closer view, and the text will adjust automatically if necessary. For the full schema, download it here.
