TYK2 belongs to the Jak family of nonreceptor tyrosine kinases which includes four mammalian members, Jak1 to 3 and TYK2. Jaks play a pivotal role in signaling via a number of cytokines and growth hormones. Jaks associate with the intracellular domains of cytokine receptors and become phosphorylated upon ligand binding. Activated Jaks phosphorylate tyrosine residues of the respective receptor chains, which, in turn, leads to the recruitment and subsequent phosphorylation of STATs. Phosphorylated STAT proteins form homo- and/or heterodimers, translocate to the nucleus, and regulate cytokine-responsive genes. TYK2 initially identified by its essential role in type I IFN signaling, was subsequently shown to be involved in signaling via a number of other cytokines. Studies of human cell lines also revealed structural functions of Tyk2 for transport and stabilization of the IFNAR1. Human TYK2 gene is mapped to chromosomal region 19p13.2.
