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.
