Platelet-derived growth factor (PDGF) is a mitogen for mesenchyme- and gliaderived cells. PDGF consists of two chains, A and B, which dimerize to form functionally distinct isoforms PGDF-AA, PDGF-AB and PDGF-BB. These three isoforms bind with different affinities to two receptor types, PDGFR-alpha and -beta, which are endowed with protein tyrosine kinase domains. PDGFR-alpha can bind to both A and B subunits of PDGF, while PDGFR-beta can only bind the B subunit. Ligand binding promotes either homo- or heterodimerization of the PDGF receptors in a specific manner. PDGF-AA induces the dimerization of two alpha receptors, PDGF-AB induces dimerization of alpha-alpha and alpha-beta, and PDGF-BB induces the formation of three types of dimers, alpha-alpha, alpha-beta and beta-beta. Translocation of the PDGFR-beta gene with the TEL gene is linked with chronic myelomonocytic leukemia (CMML), a myelodysplastic syndrome, and demonstrates the oncogenic potential of the PDGF receptors.Synonyms: Beta-type platelet-derived growth factor receptor, CD140 antigen-like family member B, PDGF Receptor beta, PDGF-R-beta
