Storage
Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.
Protocol
Specificity / Sensitivity
ROCK1 (E2G4N) Rabbit mAb recognizes endogenous levels of total ROCK1 protein. Non-specific staining was observed in placenta by immunohistochemistry. In some cell lines, this antibody cross-reacts with 45-55 kDa bands of unknown origin by western blot.
Species Reactivity:
Human, Mouse, Rat
Source / Purification
Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the central region of human ROCK1 protein.
Background
ROCK (Rho-associated kinase), a family of serine/threonine kinases, is an important downstream target of Rho-GTPase and plays an important role in Rho-mediated signaling. Two isoforms of ROCK have been identified: ROCK1 and ROCK2. ROCK is composed of N-terminal catalytic, coiled-coil, and C-terminal PH (pleckstrin homology) domains. The C-terminus of ROCK negatively regulates its kinase activity (1,2). ROCK1 is cleaved by caspase-3 at a conserved DETD1113/G sequence resulting in loss of its C-terminal inhibitory domain (3). ROCK2 is directly cleaved by granzyme B (grB). Cleavage activates ROCK and leads to phosphorylation of myosin light chain (MLC) and inhibition of myosin phosphatase (4). This phosphorylation may account for the mechanism by which Rho regulates cytokinesis, cell motility, cell membrane blebbing during apoptosis, and smooth muscle contraction (5-7).
