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
The gene EIF4EBP1 (eukaryotic translation initiation factor 4E binding protein 1) encodes a translation repressor that interacts with eukaryotic translation initiation factor 4E (eIF4E). eIF4E is a multisubunit complex that recruits 40S ribosomal subunits to the 5′ end of mRNA. The interaction of the encoded binding protein with this complex inhibits translation. The phosphorylation of eIF4Ebp1 in response to stimuli such as, UV irradiation and insulin signaling, results in dissociation of this factor from the eIF4E complex, leading to initiation of translation of mRNA. The encoded protein participates in cell proliferation, apoptosis, invasion, and metastasis. It functions as an effector molecule in mTOR (mammalian target of rapamycin complex 1) signaling pathway that regulates protein synthesis. It is found to be overexpressed in hepatocellular carcinoma tissues and serves as a potential prognostic and therapeutic target.
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:
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.
