Previous GeneCards Identifiers for ROCK2 Gene
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]

UniProtKB/Swiss-Prot for ROCK2 Gene
Protein kinase which is a key regulator of actin cytoskeleton and cell polarity. Involved in regulation of smooth muscle contraction, actin cytoskeleton organization, stress fiber and focal adhesion formation, neurite retraction, cell adhesion and motility via phosphorylation of ADD1, BRCA2, CNN1, EZR, DPYSL2, EP300, MSN, MYL9/MLC2, NPM1, RDX, PPP1R12A and VIM. Phosphorylates SORL1 and IRF4. Acts as a negative regulator of VEGF-induced angiogenic endothelial cell activation. Positively regulates the activation of p42/MAPK1-p44/MAPK3 and of p90RSK/RPS6KA1 during myogenic differentiation. Plays an important role in the timely initiation of centrosome duplication. Inhibits keratinocyte terminal differentiation. May regulate closure of the eyelids and ventral body wall through organization of actomyosin bundles. Plays a critical role in the regulation of spine and synaptic properties in the hippocampus. Plays an important role in generating the circadian rhythm of the aortic myofilament Ca(2+) sensitivity and vascular contractility by modulating the myosin light chain phosphorylation.
Rho-kinases (aka Rho-associated coiled-coil kinases or ROCKs) are serine/threonine kinases that are activated by RhoA GTPases, and are key modulators of processes involving cytoskeletal rearrangement such focal adhesion formation, cell motility and tumor cell invasion. There are two isoforms of ROCK, ROCKI (aka ROKbeta or p160ROCK) and ROCKII (aka ROKalpha), which share a high degree of structural identity in their kinase domains (92%). The two Rho-kinase isoforms have different patterns of tissue expression; ROCKII expression is highest in the brain and in muscle whereas ROCKI has a ubiquitous tissue distribution. Subcellularly, ROCKII is found in the cytosol and localizes to the cleavage furrow during cytokinesis. ROCKI 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.
