Rho-associated kinases (ROCKs) are a family of serine/threonine kinases that have important roles in Rho-mediated signaling. The structure of ROCKs (ROCK-I/ROKβ and ROCK-II/ROKα) includes an N-terminal catalytic domain, a coiled-coil region, and a C-terminal pleckstrin homology domain. The C-terminal region negatively regulates kinase activity, and this inhibitory regulation is controlled through C-terminal cleavage. Caspase-3-induced cleavage of ROCK-I and direct cleavage of ROCK-II by granzyme B activate ROCK. This leads to inhibition of myosin phosphatase and phosphorylation of myosin light chain, which causes myosin II-mediated changes in cytoskeletal dynamics. This pathway has been implicated as a downstream effector of Rho-mediated changes in cytokinesis, cell motility, apoptosis and muscle contraction.

Western blot analysis of human Jurkat cells (lane 1), rat PC12 cells (lane 2), mouse brain tissue (lane 3), and mouse SYF fibroblasts (lane 4). The blot was probed with mouse monoclonal anti-ROCK-II (Central region) antibody at 1:1000 dilution (lanes 1-4).

Clone (M276) was generated from amino acids in the central region of human ROCK-II. This sequence has high homology to rat and mouse ROCK-II, and has 50% homology to ROCK-I.
