Anti-OPTN antibody produced in rabbit (C15-1445-874)

General description

OPTN (optineurin) is a multifunctional 74kDa protein, which is composed of multiple coiled-coil domains, a leucine zipper, a ubiquitin-binding domain (UBD), and its C-terminus contains a C2H2 type zinc finger. It is expressed ubiquitously, and has predominant expression in brain, retina, heart, kidney, testis, skeletal muscle and placenta. It localizes to recycling endosomes, Golgi bodies and cytoplasm. This gene is localized to human chromosome 10p13.

Immunogen

Optineurin 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

OPTN (Optineurin) functions in several processes including vesicular trafficking from the Golgi to the plasma membrane, regulation of NF-κB, signal transduction and gene expression. It mediates the linking of myosin VI to the Golgi complex and functions in the formation of Golgi ribbon and exocytosis. It negatively regulates induction of IFNβ involved in antiviral signaling and serves as a potential target for antiviral therapy. It binds to Rab8 and regulates its association with TBC1D17, a Rab GTPase-activating protein, thus affecting Rab8-mediated processes, including the trafficking of transferrin receptor from the early endosome to the recycling endosome. Mutations in this gene cause primary open-angle glaucoma (POAG), a neurodegenerative eye disease that causes blindness.

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.

Linkage

Corresponding Antigen APREST85211.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
