Function
function
Tyrosine-protein kinase that acts as a cell-surface receptor for PDGFA, PDGFB and PDGFC and plays an essential role in the regulation of embryonic development, cell proliferation, survival and chemotaxis. Depending on the context, promotes or inhibits cell proliferation and cell migration. Plays an important role in the differentiation of bone marrow-derived mesenchymal stem cells. Required for normal skeleton development.
Catalytic activity
- L-tyrosyl-[protein] + ATP = O-phospho-L-tyrosyl-[protein] + ADP + H+
Activity regulation
Present in an inactive conformation in the absence of bound ligand. Binding of PDGFA and/or PDGFB leads to dimerization and activation by autophosphorylation on tyrosine residues.
