    text structure
  • TP53 binds the proximal promoter containing the CCAAT motif ( Tp53 represses the PDGFRB promoter, facilitating the Tp53-induced apoptosis)
  • GC-rich region (-165 to -139) of the promoter is crucial for basal promoter activity
  • promoter region is extensively demethylated following differentiation, and represents a developmentally regulated, differentially methylated region linked to PDGFRB expression
  • MAPPING cloned Y linked N status confirmed

    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • receptor tyrosine kinase, class III, phosphorylating Tyr residues at the C-terminus of PTPN11 creating a binding site for the SH2 domain of GRB2
  • mitogen for mesenchyme-derived cells, including fibroblasts and smooth muscle
  • phosphorylates GRK2 tyrosyl residues and thereby activates GRK2, which then serine-phosphorylates and desensitizes the PDGFRbeta
  • PDGFRB signaling is crucial for neuroprotection, endogenous tissue repair, and functional recovery after stroke by targeting neurons,pericyte/vascular smooth muscle cells, and astrocytes
  • required for the development of mesenchymal cell types, and plays a diverse role in the function of fibroblasts in tissue homeostasis and regeneration
  • PDGFRB-mediated signaling plays a key role in morphine tolerance
  • has an essential role in vascular progenitor cell signaling (pMID: 31031011)
  • CELLULAR PROCESS cell life, proliferation/growth
  • PDGFRB-AKT1 signaling in brain pericytes may play various important roles leading to neuroprotection after ischemic stroke
  • a component
  • homodimerizing and heterodimerizing with PDGFRA
    small molecule nucleotide,
  • ATP
  • protein
  • binds specifically to PDGFRA and has a tyrosine-protein kinase activity
  • interacting with NRP1 (influences ligand-induced PDGFRB homodimer signalling)
  • important interactive relationship between SLC6A4 and the PDGFRB in the production of pulmonary artery smooth muscle cell proliferation triggered by PDGF that may be important in pulmonary hypertension (PH)
  • LRP6 forms a complex with PDGFRB and promotes its degradation
  • SH2B3 is a negative regulator of PDGFR signaling
  • in aortic smooth muscle cells, TGM2 specifically amplifies the activation of PDGFRB and its multiple downstream signaling targets in response to PDGF-BB
  • ETV6-PDGFRB antagonizes the effects of ETV6 and IRF8 on PTPN13 transcription
  • PDGFRB/MAPK1 signalling pathway triggered by FGF2 plays an important role in the proliferation and migration of endothelial progenitor cells
  • involved in angiogenesis and in the regulation of inorganic phosphate (Pi) transport in vascular smooth
  • muscle cells via SLC20A1
  • PDGFRB expression was upregulated by NOTCH3 ligand induction or by activated forms of the NOTCH3 receptor
  • affects the intracellular sorting of activated PDGFRB and the migration, proliferation and tumorigenicity of cells stimulated by PDGF
  • cell & other
    activated by constitutively activated through amino-acid(s) substitution in a WW-like domain (phosphoserine- or phosphothreonine binding)
