>cd05038 PTKc_Jak_rpt2 Catalytic (Repeat 2) Domain of the Protein Tyrosine Kinases, Janus kinases. Protein Tyrosine Kinase (PTK) family; Janus kinase (Jak) subfamily; catalytic (c) domain (repeat 2). The Jak subfamily is composed of Jak1, Jak2, Jak3, TYK2, and similar proteins. The PTKc family is part of a larger superfamily that includes the catalytic domains of other kinases such as protein serine/threonine kinases, RIO kinases, and phosphoinositide 3-kinase (PI3K). PTKs catalyze the transfer of the gamma-phosphoryl group from ATP to tyrosine (tyr) residues in protein substrates. Jak subfamily proteins are cytoplasmic (or nonreceptor) tyr kinases containing an N-terminal FERM domain, followed by a Src homology 2 (SH2) domain, a pseudokinase domain, and a C-terminal tyr kinase catalytic domain. Most Jaks are expressed in a wide variety of tissues, except for Jak3, which is expressed only in hematopoietic cells. Jaks are crucial for cytokine receptor signaling. They are activated by aut
