背景
The protein encoded by this gene is a member of the platelet-derived growth factor family.
The four members of this family are mitogenic factors for cells of mesenchymal origin and
are characterized by a core motif of eight cysteines. This gene product appears to form only
homodimers. It differs from the platelet-derived growth factor alpha and beta polypeptides in
having an unusual N-terminal domain, the CUB domain. Alternatively spliced transcript
variants have been found for this gene.
