Platelet-derived growth factor receptor (PDGFR) exists as two closely related receptor tyrosine kinases, PDGFR- α and PDGFR- β. PDGFR consists of five extracellular Ig-like domains involved in ligand binding, a single transmembrane domain, and two intracellular tyrosine kinase domains split by a kinase insert region. Upon ligand binding, PDGFR dimerizes into one of three forms (α/ α, α/ β, or β/ β) in response to the isoform of the PDGF ligand. Dimerization of the receptor results in autophosphorylation of multiple tyrosines (579, 581, 716, 740, 751, 763, 771, 775, 857, 1009, and 1021) in the cytoplasmic domain, recruiting and binding many cytoplasmic signaling and adaptor proteins containing SH2 domains. The PDGF/PDGFR cellular signaling system is essential for the embryonic development of various tissue types and is also important in angiogenesis and wound healing. The characterization of PDGFR overexpression in many solid tumor types and its role in angiogenesis make it an attractive target for anti-cancer therapeutic development.
