CC -!- FUNCTION: Tyrosine-protein kinase that acts as cell-surface receptor
CC for homodimeric PDGFB and PDGFD and for heterodimers formed by PDGFA
CC and PDGFB, and plays an essential role in the regulation of embryonic
CC development, cell proliferation, survival, differentiation, chemotaxis
CC and migration. Plays an essential role in blood vessel development by
CC promoting proliferation, migration and recruitment of pericytes and
CC smooth muscle cells to endothelial cells.
CC {ECO:0000256|PIRNR:PIRNR500948}.
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 ChEBI:CHEBI:61978, ChEBI:CHEBI:456216; EC=2.7.10.1;
CC Evidence={ECO:0000256|ARBA:ARBA00051243,
CC ECO:0000256|PIRNR:PIRNR500948};
CC -!- SUBUNIT: Interacts with homodimeric PDGFB and PDGFD, and with
CC heterodimers formed by PDGFA and PDGFB. May also interact with
CC homodimeric PDGFC. Monomer in the absence of bound ligand. Interaction
CC with homodimeric PDGFB, heterodimers formed by PDGFA and PDGFB or
CC homodimeric PDGFD, leads to receptor dimerization, where both PDGFRA
CC homodimers and heterodimers with PDGFRB are observed. Interacts with
CC SH2B2/APS. Interacts directly (tyrosine phosphorylated) with SHB.
CC Interacts (tyrosine phosphorylated) with PIK3R1 and RASA1. Interacts
CC (tyrosine phosphorylated) with CBL. Interacts (tyrosine phosphorylated)
CC with SRC and SRC family kinases. Interacts (tyrosine phosphorylated)
CC with PIK3C2B, maybe indirectly. Interacts (tyrosine phosphorylated)
CC with SHC1, GRB7, GRB10 and NCK1. Interaction with GRB2 is mediated by
CC SHC1. Interacts (via C-terminus) with NHERF1.
CC {ECO:0000256|ARBA:ARBA00066051}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|PIRNR:PIRNR500948};
CC Single-pass type I membrane protein {ECO:0000256|PIRNR:PIRNR500948}.
CC Cytoplasmic vesicle {ECO:0000256|ARBA:ARBA00004541,
CC ECO:0000256|PIRNR:PIRNR500948}. Lysosome lumen
CC {ECO:0000256|PIRNR:PIRNR500948}. 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:PIRNR500948, ECO:0000256|RuleBase:RU000311}.
