>cd05054 PTKc_VEGFR Catalytic Domain of the Protein Tyrosine Kinases, Vascular Endothelial Growth Factor Receptors. Protein Tyrosine Kinase (PTK) family; Vascular Endothelial Growth Factor Receptor (VEGFR) subfamily; catalytic (c) domain. The VEGFR subfamily consists of VEGFR1 (Flt1), VEGFR2 (Flk1), VEGFR3 (Flt4), 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. VEGFR subfamily members are receptor tyr kinases (RTKs) containing an extracellular ligand-binding region with seven immunoglobulin (Ig)-like domains, a transmembrane segment, and an intracellular catalytic domain. In VEGFR3, the fifth Ig-like domain is replaced by a disulfide bridge. The binding of VEGFRs to their ligands, the VEGFs, leads to recepto
