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.
