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 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.
CC {ECO:0000256|PIRNR:PIRNR500948}.
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.
