Gene Information

General description

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. ROCK1 (Rho-associated, coiled-coil containing protein kinase 1) gene encodes a 160kDa serine/threonine kinase that specifically binds to GTP-bound Rho. It is a platelet protein with 1354 amino acids. It has a Ser/Thr kinase domain in its N-terminus, followed by a 600 amino acid long coiled-coil structure. The C-terminal region contains a cysteine-rich zinc finger-like motif and a pleckstrin homology region.

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

ROCK1 (Rho-associated, coiled-coil containing protein kinase 1), an effector of the small GTPase Rho, functions along with the small GTPase Rho in phosphorylating LIM-kinase 1, which in turn phosphorylates cofilin, an actin-depolymerizing factor, thereby regulating actin cytoskeletal reorganization. It is capable of inducing Ca2+-independent contraction of smooth muscle. Activation of ROCK1 by cleavage with caspase-3 stimulates the formation of membrane bleb formation in apoptotic cells. It phosphorylates and regulates zipper-interacting protein kinase (ZIPK) that mediates Ca2+-independent phosphorylation of both smooth muscle and non-muscle myosin.

Features and Benefits

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.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

Increased phosphorylation of myosin light chain (MLC) is necessary for the dynamic membrane blebbing that is observed at the onset of apoptosis. Here we identify ROCK I, an effector of the small GTPase Rho, as a new substrate for caspases.
