JAK3 (Tyrosine-protein kinase JAK3) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. The public catalogues list it as a drug target, an oncogene driver and a biomarker, and an approved or late-stage drug is recorded against it. Tied to Myeloproliferative neoplasms, Leukaemia, Non-Hodgkin lymphoma and 5 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
Non-receptor tyrosine kinase involved in various processes such as cell growth, development, or differentiation. Mediates essential signalling events in both innate and adaptive immunity and plays a crucial role in haematopoiesis during T-cells development. In the cytoplasm, plays a pivotal role in signal transduction via its association with type I receptors sharing the common subunit gamma such as IL2R, IL4R, IL7R, IL9R, IL15R and IL21R. Following ligand binding to cell surface receptors, phosphorylates specific tyrosine residues on the cytoplasmic tails of the receptor, creating docking sites for STATs proteins. Subsequently, phosphorylates the STATs proteins once they are recruited to the receptor. Phosphorylated STATs then form homodimer or heterodimers and translocate to the nucleus to activate gene transcription. Location: Endomembrane system; Cytoplasm (UniProt). Locus 19p13.11 (HGNC).
