Rho-kinases (aka Rho-associated coiled-coil kinases or ROCKs) are serine/threonine kinases activated by RhoA GTPases. They are modulators of processes involving cytoskeletal rearrangement such as focal adhesion formation, cell motility and tumor cell invasion.

Selective ROCK inhibitor; inhibits ROCK1 (p160 ROCK) and ROCK2

There are two isoforms of ROCK, ROCK1 (aka ROKβ or p160 ROCK) and ROCK2 (aka ROKα), which share a high degree of structural identity in their kinase domains (92%).

The two Rho-kinase isoforms have different patterns of tissue expression; ROCK2 expression is highest in the brain and in muscle whereas ROCK1 has a ubiquitous tissue distribution. Subcellularly, ROCK2 is found in the cytosol and localizes to the cleavage furrow during cytokinesis. ROCK1 is thought to colocalize with the centrosomes. ROCKs phosphorylate a number of proteins involved in actin filament assembly and contraction (e.g. LIM Kinases, MLCK, ERM proteins). Other downstream targets of the Rho kinases include signal transduction molecules such as IRS-1 and PI 3-K/AKT.
