Anti-RNF139 antibody produced in rabbit

RING finger protein 139 recombinant protein epitope signature tag (PrEST)

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.

RNF139 (ring finger protein 139) gene encodes a endoplasmic reticulum protein that contains a RING-H2 finger required for Ub ligase activity and a sterol-sensing domain. It possesses E3-ubiquitin ligase activity. It negatively regulates cell proliferation via mechanisms involving G2/M arrest, decreased DNA synthesis and cell death. It acts as a putative tumor suppressor. It represses genes involved in the biosynthesis of cholesterol and fatty acids that are transcriptionally regulated by the sterol response element binding proteins (SREBPs), thus, establishing a link between growth control and the cholesterol/lipid homeostasis pathway. It inhibits the transport of sterol regulatory element-binding protein-2 (SREBP-2) from ER to Golgi. It is linked to the development of hereditary kidney cancer. The protein is required for the dislocation of MHC I (major histocompatibility complex class I) from the ER.

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.
