ROCK2（Rho associated coiled-coil containing protein kinase 2），癌症关联基因，基因ID：9475，该基因编码的蛋白质是一种丝氨酸/苏氨酸激酶，调节胞质分裂、平滑肌收缩、肌动蛋白应力纤维和局灶性粘连的形成以及c-fos血清反应元件的激活这种蛋白质是ROCK1的一种同工酶，是小GTPase Rho的靶标[由RefSeq提供，2008年7月]The protein encoded by this gene is a serine/threonine kinase that regulates cytokinesis， smooth muscle contraction， the formation of actin stress fibers and focal adhesions， and the activation of the c-fos serum response element. This protein， which is an isozyme of ROCK1 is a target for the small GTPase Rho. [provided by RefSeq， Jul 2008]。
