ROCK-1 (Rho-associated Coiled-coil-containing Protein Kinase 1, ROCK1, MGC131603, MGC43611, NY-REN-35 Antigen, p160 ROCK1, p160ROCK, Renal Carcinoma Antigen NY-REN-35, Rho-associated Protein Kinase 1)

Rho Kinase Beta, a 160kD small-GTP-effector protein, is a serine/threonine kinase involved in the induction of focal adhesions and stress fibers, and can play a major role in vascular smooth muscle contraction, malignant cell transformation, tumor invasion and metastasis. ROCK1 is identified as a substrate for caspases and is cleaved by caspase 3 at a conserved DETD1113/G sequence which removes its carboxy-terminal inhibitory domain, resulting in a constitutively active 130kD ROCK1 kinase. Proteolytic activation of ROCK1 by caspase is critical for its role in regulating the actin cytoskeleton and Myosin Light Chain (MLC) phosphorylation. Increased phosphorylation of MLC is important for membrane blebbing, a cellular event that occurs at the onset of apoptosis.\n\nApplications: \nSuitable for use in Western Blot and Immunoprecipitation. Other applications not tested.\n\nRecommended Dilution:\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20 degrees C. Aliquots are stable for at least 3 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
