pubmed:abstractText |
32D cells transfected with the human alpha platelet-derived growth factor receptor (alpha PDGFR) bind PDGF-AA, -AB, and -BB isoforms with high affinity, and the binding of each can be efficiently competed by all three isoforms. In an effort to develop better understanding of spatial relationships of binding sites for PDGF-AA and -BB, we constructed an alpha PDGFR mutant which deleted amino acids 150-189 within its extracellular domain. This mutant showed a marked decrease in high affinity binding sites for PDGF-AA without comparable alteration in affinity for PDGF-BB. These findings imply that the high affinity binding sites for PDGF-AA and PDGF-BB in the alpha PDGFR extracellular domain are not structurally coincident.
