ANTI-COPS2 (C005B-204768)

General description

The gene COP9 signalosome complex subunit 2 (COPS2) is mapped to human chromosome 15q21.2. The protein is localized in the cytoplasm and the nucleus.

Immunogen

COP9 signalosome complex subunit 2 recombinant protein epitope signature tag (PrEST)

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

COP9 signalosome complex subunit 2 (COPS2) is a subunit of COP9 (constitutive photomorphogenesis 9) signalosome (CSN). CSN is responsible for deneddylation of cullins and thus regulates protein degradation. COPS2 knockdown inhibits CSN deneddylase function. Loss of COPS2 also results in non-apoptotic cell death. CSN phosphorylates and degrades p53. Disruption of the COPS2 subunit in mice causes deficiencies in cell proliferation, accumulation of p53 and cyclin E, and embryonic death at a very early stage. COPS2 interacts with CUL1, a subunit of SCF (Skp, Cullin, F-box containing complex) ubiquitin ligase, thus helping CSN association with catalytic core of SCF. COPS2 also interacts with the anaphase-promoting complex (APC/C) and affect the APC/C-mediated cell cycle regulation.

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.
