Description_x000D_ General description_x000D_ The gene EIF4G3 (eukaryotic translation initiation factor 4 γ 3) is mapped to human chromosome 1p36.12. It is widely expressed in human tissues and is a functional homolog of EIF4G1. The encoded protein directly binds to EIF4E (eukaryotic translation initiation factor 4E), EIF4A and EIF3._x000D_ Immunogen_x000D_ Eukaryotic translation initiation factor 4 gamma 3 recombinant protein epitope signature tag (PrEST)_x000D_ Application_x000D_ All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry._x000D_ 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.

LLC_x000D_ Biochem/physiol Actions_x000D_ EIF4G3 (eukaryotic translation initiation factor 4 γ 3) is a crucial component of the translation initiation complex EIF4F (eukaryotic translation initiation factor 4F). During translational initiation, it is responsible for recruiting the mRNA. In Drosophila, EIF4G3 also plays a role in spermatogenesis. The EIF4G3 mRNA is a target of tumor suppressor microRNA miR-520c-3p, leading to senescence in tumor cells. The EIF4G3 gene is upregulated in DLBCL (diffuse large B cell lymphoma). Mutation in the gene might be linked with SFG (superior frontal gyrus) volumes which are associated with schizophrenia._x000D_ Features and Benefits_x000D_ 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._x000D_ Every Prestige Antibody is tested in the following ways:_x000D_ • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues._x000D_ • Protein array of 364 human recombinant protein fragments._x000D_ • Validated for multiple commonly used applications such as IHC (Immunohistochemistry), IF (Immunofluorescence), and WB (Western Blot)_x000D_ Linkage_x000D_ Corresponding Antigen APREST76528.
