Mouse Anti-Platelet Derived Growth Factor Receptor, alpha (Platelet-derived Growth Factor Receptor alpha, PDGFR alpha, PDGF-R-alpha, PDGFRa, PDGFR-A, Alpha Platelet-derived Growth Factor Receptor, CD140a, CD140a Antigen, MGC74795, PDGF alpha Chain, Platelet-derived Growth Factor Receptor 2, PDGFR2, PDGFR-2)
Platelet-derived growth factor (PDGF) exerts its stimulatory effects on cell growth and motility by binding to two related protein tyrosine kinase receptors, which can associate as three dimer forms (alpha/alpha, alpha/beta, beta/beta) with variable binding specificity for the PDGF ligands (1,2). The total number of the two receptor subunits and the ratio expressed varies between cell types and appears to account for the variable responsiveness of different cell types to PDGF (3). Ligand binding induces receptor dimerization and autophosphorylation, allowing binding and activation of cytoplasmic SH2 domain-containing signal transduction molecules including Grb2, Src, GAP, PI3 kinase, PLCgamma and Nck.
