Description_x000D_ General description_x000D_ ROCK (Rho-associated, coiled-coil containing protein kinase) has two isoforms, ROCK1 and ROCK2 that share 65% sequence similarity. ROCK has three domains that include the N-terminal catalytic domain (CAT), a middle coiled-coil domain that mediates homodimerization, and Rho-binding (RB) and pleckstrin homology (PH) domains (RB/PH domain) at the C-terminus. The RB/PH domain acts as an autoinhibitory domain and suppresses the kinase activity of CAT._x000D_ Immunogen_x000D_ ρ-Associated protein kinase 2 recombinant protein epitope signature tag (PrEST)_x000D_ Application_x000D_ Anti-ROCK2 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting.

LLC_x000D_ Biochem/physiol Actions_x000D_ ROCK2 (Rho-associated, coiled-coil containing protein kinase 2) gene encodes a serine/threonine kinase that serves as an effector for the small GTPase RhoA. ROCK2 is localized to the nucleus and is capable of associating with and phosphorylating p300, thereby increasing the acetyltransferase activity of p300. ROCK functions in several cellular activities, such as regulation of actin cytoskeleton and cell polarity, cell adhesion, cytokinesis, and gene expression. It inhibits keratinocyte terminal differentiation. In ROCK2, the RB/PH domain is cleaved by granzyme B to generate an active form that is involved in the generation of cytoplasmic apoptotic bleb. It interacts with nucleophosmin/B23 and initiates centrosome duplication._x000D_ Features and Benefits_x000D_ Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section._x000D_ Every Prestige Antibody is tested in the following ways:_x000D_ • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues._x000D_ • Protein array of 364 human recombinant protein fragments._x000D_ • Validated for multiple commonly used applications such as IHC (Immunohistochemistry), IF (Immunofluorescence), and WB (Western Blot)_x000D_ Linkage_x000D_ Corresponding Antigen APREST71422.
