>cd05037 PTK_Jak_rpt1 Pseudokinase (Repeat 1) Domain of the Protein Tyrosine Kinases, Janus kinases. Protein Tyrosine Kinase (PTK) family; Janus kinase (Jak) subfamily; pseudokinase domain (repeat1). The Jak subfamily is composed of Jak1, Jak2, Jak3, TYK2, and similar proteins. The PTKc (catalytic domain) family to which this subfamily belongs, 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 catalytic tyr kinase domain. The pseudokinase domain shows similarity to tyr kinases but lacks crucial residues for catalytic activity and ATP binding. It modulates the ki
