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. {ECO:0000256|PIRNR:PIRNR500950}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-tyrosyl-[protein] + ATP = O-phospho-L-tyrosyl-[protein] +
CC ADP + H(+); Xref=Rhea:RHEA:10596, Rhea:RHEA-COMP:10136, Rhea:RHEA-
CC COMP:20101, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:46858,
CC ChEBI:CHEBI:61978, ChEBI:CHEBI:456216; EC=2.7.10.1;
CC Evidence={ECO:0000256|ARBA:ARBA00051243};
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.
CC {ECO:0000256|PIRNR:PIRNR500950}.
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. Interacts (tyrosine phosphorylated) with SHB
CC (via SH2 domain). Interacts (tyrosine phosphorylated) with SHF (via SH2
CC domain). Interacts (tyrosine phosphorylated) with SRC (via SH2 domain).
CC Interacts (tyrosine phosphorylated) with PIK3R1. Interacts (tyrosine
CC phosphorylated) with PLCG1 (via SH2 domain). Interacts (tyrosine
CC phosphorylated) with CRK, GRB2 and GRB7. Interacts with CD248; this
CC interaction promotes PDGF receptor signaling pathway.
CC {ECO:0000256|ARBA:ARBA00062037}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|ARBA:ARBA00004251,
CC ECO:0000256|PIRNR:PIRNR500950}; Single-pass type I membrane protein
CC {ECO:0000256|ARBA:ARBA00004251, ECO:0000256|PIRNR:PIRNR500950}. Cell
CC projection, cilium {ECO:0000256|ARBA:ARBA00004138}. Golgi apparatus
CC {ECO:0000256|ARBA:ARBA00004555}. Membrane
CC {ECO:0000256|RuleBase:RU000311}; Single-pass type I membrane protein
CC {ECO:0000256|RuleBase:RU000311}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Tyr protein
CC kinase family. CSF-1/PDGF receptor subfamily.
CC {ECO:0000256|PIRNR:PIRNR500950, ECO:0000256|RuleBase:RU000311}.
