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 -!- 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. {ECO:0000256|ARBA:ARBA00064866}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|ARBA:ARBA00004251};
CC Single-pass type I membrane protein {ECO:0000256|ARBA:ARBA00004251}.
CC Membrane {ECO:0000256|RuleBase:RU000311}; Single-pass type I membrane
CC protein {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|RuleBase:RU000311}.
