这个基因编码的蛋白质是一个二硫键连接的同三聚体蛋白的亚单位。该蛋白是一种粘附性糖蛋白，介导细胞间和细胞间的相互作用该蛋白可与纤维蛋白原、纤维粘连蛋白、层粘连蛋白、V型胶原和整合素α-V/β-1结合。这种蛋白在血小板聚集、血管生成和肿瘤发生中起作用[由RefSeq提供，2008年7月]
The protein encoded by this gene is a subunit of a disulfide-linked homotrimeric protein. This protein is an adhesive glycoprotein that mediates cell-to-cell and cell-to-matrix interactions. This protein can bind to fibrinogen, fibronectin, laminin, type V collagen and integrins alpha-V/beta-1. This protein has been shown to play roles in platelet aggregation, angiogenesis, and tumorigenesis. [provided by RefSeq, Jul 2008]
