NCIt definition : Platelet-derived growth factor receptor beta (1106 aa, 124 kDa) is encoded by the
human PDGFRB gene. This protein plays a role in tyrosine phosphorylation and ligand-dependent
signal transduction.;
NCIt note : The identity of the growth factor bound to a receptor monomer determines whether the
functional receptor is a homodimer or a heterodimer, composed of both platelet-derived
growth factor receptor alpha and beta polypeptides. This gene is flanked on chromosome
5 by the genes for granulocyte-macrophage colony-stimulating factor and macrophage-colony
stimulating factor receptor; all three genes may be implicated in the 5-q syndrome.
A translocation between chromosomes 5 and 12, that fuses this gene to that of the
translocation, ETS, leukemia gene, results in chronic myelomonocytic leukemia. (from
