>cd05053 PTKc_FGFR Catalytic Domain of the Protein Tyrosine Kinases, Fibroblast Growth Factor Receptors. Protein Tyrosine Kinase (PTK) family; Fibroblast Growth Factor Receptor (FGFR) subfamily; catalytic (c) domain. The FGFR subfamily consists of FGFR1, FGFR2, FGFR3, FGFR4, 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. FGFR subfamily members are receptor tyr kinases (RTKs) containing an extracellular ligand-binding region with three immunoglobulin-like domains, a transmembrane segment, and an intracellular catalytic domain. The binding of FGFRs to their ligands, the FGFs, and to heparin/heparan sulfate (HS) results in the formation of a ternary complex, which leads to receptor dimerization and activation,
