>cd05081 PTKc_Jak2_Jak3_rpt2 Catalytic (Repeat 2) Domain of the Protein Tyrosine Kinases, Janus kinases 2 and 3. Protein Tyrosine Kinase (PTK) family; Janus kinase 2 (Jak2) and Jak3; catalytic (c) domain (repeat 2). 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. Jak2 and Jak3 are members of the Janus kinase (Jak) subfamily of proteins, which 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 catalytic tyr kinase domain. Jaks are crucial for cytokine receptor signaling. They are activated by autophosphorylation upon cytokine-induced receptor aggregation, and subsequently trigger downstream signaling events such as th
