該基因編碼的蛋白質主要存在于內皮細胞和血管中，參與細胞形態變化和表皮生長因子誘導的細胞遷移。能增強血管內皮生長因子受體-2/激酶插入結構域受體的活化，并促進內化激酶插入結構域受體的蛋白水解。該基因可能在血管生成相關疾病中發揮作用。選擇性剪接導致多個轉錄變體。
The protein encoded by this gene is primarily found in endothelial cells and blood vessels, where it is involved in cell shape changes and EGF-induced cell migration. It can enhance the activation of vascular endothelial growth factor receptor-2/kinase insert domain receptor and also promote the proteolysis of internalized kinase insert domain receptor. This gene may play a role in angiogenesis-related diseases. Alternative splicing results in multiple transcript variants.
