>cd05102 PTKc_VEGFR3 Catalytic Domain of the Protein Tyrosine Kinase, Vascular Endothelial Growth Factor Receptor 3. Protein Tyrosine Kinase (PTK) family; Vascular Endothelial Growth Factor Receptor 3 (VEGFR3); catalytic (c) domain. 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. VEGFR3 (or Flt4) is a member of the VEGFR subfamily of proteins, which 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 receptor dimerization, activation, and intracellular signaling. V
