Catalytic activity:ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. ,Disease:A chromosomal aberration involving PDGFRB is a cause in many instances of chronic myeloproliferative disorder with eosinophilia (MPE) [MIM:131440]. Translocation t (5;12) with ETV6 on chromosome 12 creating an PDGFRB-ETV6 fusion protein. ,Disease:A chromosomal aberration involving PDGFRB is found in a form of chronic myelomonocytic leukemia (CMML) . Translocation t (5;12) (q33;p13) with EVT6/TEL. It is characterized by abnormal clonal myeloid proliferation and by progression to acute myelogenous leukemia (AML) . ,Disease:A chromosomal aberration involving PDGFRB may be a cause of acute myelogenous leukemia. Translocation t (5;14) (q33;q32) with TRIP11. The fusion protein may be involved in clonal evolution of leukemia and eosinophilia. ,Disease:A chromosomal aberration involving PDGFRB may be a cause of juvenile myelomonocytic leukemia. Translocation t (5;17) (q33;p11.2) with SPECC1. ,Disease:A chromosomal aberration involving PDGFRB may be the cause of a myeloproliferative disorder (MBD) associated with eosinophilia. Translocation t (1;5) (q23;q33) that forms a PDE4DIP-PDGFRB fusion protein. ,Function:Receptor that binds specifically to PDGFB and PDGFD and has a tyrosine-protein kinase activity. Phosphorylates Tyr residues at the C-terminus of PTPN11 creating a binding site for the SH2 domain of GRB2. ,similarity:Belongs to the protein kinase superfamily. Tyr protein kinase family. ,similarity:Belongs to the protein kinase superfamily. Tyr protein kinase family. CSF-1/PDGF receptor subfamily. ,similarity:Contains 1 protein kinase domain. ,similarity:Contains 5 Ig-like C2-type (immunoglobulin-like) domains. ,subunit:Homodimer , and heterodimer with PDGFRA. Interacts with APS. The autophosphorylated form interacts directly with SHB and with PIK3C2B , maybe indirectly. ,
