THBS2（thrombospondin 2），癌症关联基因，基因ID：7058，该基因编码的蛋白质属于凝血酶敏感蛋白家族。是一种二硫键联的同源三聚体糖蛋白，介导细胞间和细胞间和基质间的相互作用。这种蛋白已被证明是一种有效的肿瘤生长和血管生成抑制剂。对小鼠的研究表明，这种蛋白可能调节间充质细胞的细胞表面特性，并参与细胞粘附和迁移。The protein encoded by this gene belongs to the thrombospondin family. It is a disulfide-linked homotrimeric glycoprotein that mediates cell-to-cell and cell-to-matrix interactions. 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.关联癌症：结直肠癌。
