MSH: A PDGF receptor that binds specifically to the PDGF-B chain. It contains a protein-tyrosine kinase activity that is involved in SIGNAL TRANSDUCTION.,NCI: Platelet-Derived Growth Factor Receptor, Beta Polypeptide, encoded by the PDGFRB gene, is a cell surface tyrosine kinase receptor for members of the platelet-derived growth factor family. These growth factors are mitogens for cells of mesenchymal origin. 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 LocusLink)
