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

TRIM50 (Tripartite motif containing 50) is involved in the ubiquitination pathway. Its RING domain directly conjugates with E2 ubiquitin proving its ability to act as an E3 ubiquitin ligase. TRIM50 plays a major role in the organization of tubulovesicular structure in cytoskeleton network by forming canaliculi and microvilli in parietal cells. It can identify the phosphorylated state of phosphoinositol lipids. Study shows the association of TRIM50 with the Williams-Beuren syndrome (WBS), a neurodevelopmental and multisystemic disease. It has been reported in the study that the ubiquitin-mediated proteasome pathway mediated by TRIM50 might be involved in the WBS phenotype.

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.

General description

TRIM50 (Tripartite motif containing 50) is an E3 ubiquitin ligase belonging to the TRIpartite motif gene family. It is mapped to chromosome 7q11.23. It is expressed in gastric parietal cells, intestine, liver, brain and it is localized mainly in the tubulovesicular and canalicular membranes.
