RX PubMed=8358864; DOI=10.1002/dvg.1020140305; RA Jones S.D., Ho L., Smith J.C., Yordan C., Stiles C.D., Mercola M.; RT "The Xenopus platelet-derived growth factor alpha receptor: cDNA cloning RT and demonstration that mesoderm induction establishes the lineage-specific RT pattern of ligand and receptor gene expression."; RL Dev. Genet. 14:185-193(1993). CC -!- FUNCTION: Tyrosine-protein kinase that acts as a cell-surface receptor CC for pdgfa, pdgfb and pdgfc and plays an essential role in the CC regulation of embryonic development, cell proliferation, survival and CC chemotaxis. Depending on the context, promotes or inhibits cell CC proliferation and cell migration. Plays an important role in the CC differentiation of bone marrow-derived mesenchymal stem cells. Required CC for normal skeleton development. Required for normal development of the CC gastrointestinal tract. Plays a role in cell migration and chemotaxis CC in wound healing. Plays a role in platelet activation, secretion of CC agonists from platelet granules, and in thrombin-induced platelet CC aggregation. Binding of its cognate ligands - homodimeric pdgfa, CC homodimeric pdgfb, heterodimers formed by pdgfa and pdgfb or CC homodimeric pdgfc -leads to the activation of several signaling CC cascades; the response depends on the nature of the bound ligand and is CC modulated by the formation of heterodimers between pdgfra and pdgfrb. CC Phosphorylates pik3r1, plcg1, and ptpn11. Activation of plcg1 leads to CC the production of the cellular signaling molecules diacylglycerol and CC inositol 1,4,5-trisphosphate, mobilization of cytosolic Ca(2+) and the CC activation of protein kinase C. Phosphorylates pik3r1, the regulatory CC subunit of phosphatidylinositol 3-kinase, and thereby mediates CC activation of the akt1 signaling pathway. Mediates activation of hras CC and of the MAP kinases mapk1/erk2 and/or mapk3/erk1. Promotes CC activation of stat family members stat1, stat3 and stat5a and/or CC stat5b. Receptor signaling is down-regulated by protein phosphatases CC that dephosphorylate the receptor and its down-stream effectors, and by CC rapid internalization of the activated receptor (By similarity). CC {ECO:0000250}. CC -!- CATALYTIC ACTIVITY: CC Reaction=ATP + L-tyrosyl-[protein] = ADP + H(+) + O-phospho-L-tyrosyl- CC [protein]; Xref=Rhea:RHEA:10596, Rhea:RHEA-COMP:10136, Rhea:RHEA- CC COMP:10137, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:46858, CC ChEBI:CHEBI:82620, ChEBI:CHEBI:456216; EC=2.7.10.1; CC Evidence={ECO:0000255|PROSITE-ProRule:PRU10028}; CC -!- ACTIVITY REGULATION: Present in an inactive conformation in the absence CC of bound ligand. Binding of pdgfa and/or pdgfb leads to dimerization CC and activation by autophosphorylation on tyrosine residues (By CC similarity). {ECO:0000250}. CC -!- SUBUNIT: Interacts with homodimeric pdgfa, pdgfb and pdgfc, and with CC heterodimers formed by pdgfa and pdgfb. Monomer in the absence of bound CC ligand. Interaction with dimeric pdgfa, pdgfb and/or pdgfc leads to CC receptor dimerization, where both pdgfra homodimers and heterodimers CC with pdgfrb are observed (By similarity). {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P16234}; CC Single-pass type I membrane protein {ECO:0000250|UniProtKB:P16234}. CC Cell projection, cilium {ECO:0000250|UniProtKB:P26618}. Golgi apparatus CC {ECO:0000250|UniProtKB:P26618}. CC -!- PTM: Ubiquitinated, leading to its internalization and degradation. CC {ECO:0000250|UniProtKB:P26618}. CC -!- PTM: Autophosphorylated on tyrosine residues upon ligand binding. CC Autophosphorylation occurs in trans, i.e. one subunit of the dimeric CC receptor phosphorylates tyrosine residues on the other subunit (By CC similarity). {ECO:0000250}. CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Tyr protein CC kinase family. CSF-1/PDGF receptor subfamily. {ECO:0000255|PROSITE- CC ProRule:PRU00159}.
