Thrombospondin 2 is an adhesive glycoprotein that mediates cell-to-cell and cell-to-matrix interactions. It can bind to fibrinogen, fibronectin, laminin and type V collagen. This protein has been shown to function as a potent inhibitor of tumor growth and angiogenesis. Studies of the mouse counterpart suggest that this protein may modulate the cell surface properties of mesenchymal cells and be involved in cell adhesion and migration.
