該基因編碼的蛋白是血小板衍生生長因子/血管內皮生長因子（pdgf/vegf）家族的成員。編碼蛋白促進血管生成和內皮細胞生長，并能影響血管的通透性。前蛋白進一步被切割成一個完全加工的形式，可以結合和激活vegfr-2和vegfr-3受體。
The protein encoded by this gene is a member of the platelet-derived growth factor/vascular endothelial growth factor (PDGF/VEGF) family. The encoded protein promotes angiogenesis and endothelial cell growth, and can also affect the permeability of blood vessels. The proprotein is further cleaved into a fully processed form that can bind and activate VEGFR-2 and VEGFR-3 receptors.
