Anti-RPN1 antibody produced in rabbit

Ribophorin I (RPN1) is a type I transmembrane glycoprotein of 583 amino acids encoded by the gene mapped to human chromosome 3q21. It is one of the subunits of oligosaccharyltransferase (OST) complex expressed predominantly in endoplasmic reticulum membrane. The encoded protein is characterized with leucine-rich-repeat-like (LRR-like) domain involved in binding several ligands to the proteasome.

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.

Ribophorin I (RPN1) promotes N- glycosylation of potential substrates, which are near to the catalytic subunit of the oligosaccharyltransferase (OST) complex. RPN1 functions as a part of regulatory subunit of proteasome and helps in binding proteins with ubiquitin-like (UBL) domains to the proteasome. The encoded protein might associate with signal recognition complexes and facilitate the transfer of secretory and membrane proteins across the microsomal membrane. Ribophorin I directly interacts with μ-opioid receptor (MOR) and modulates its cell surface expression. This protein associates with misfolded ribonuclease A, but not with the natural form, proposing that it might act as a chaperone that identifies misfolded proteins inside cells.

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.
