Anti-UPF3A antibody produced in rabbit

Up-frameshift suppressor 3 homolog A (UPF3A) shuttles between nucleus and cytoplasm. In humans there are two paralogs of UPF3, UPF3A and UPF3B. UPF3A transcript is highly expressed in testis, uterus, muscle, fetal brain and spinal cord.

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.

Up-frameshift suppressor-3 homolog A (UPF3A) is involved in nonsense-mediated decay (NMD), an RNA decay pathway. A mutant of UPF3A which is unable to exit the nucleus does not participate in nonsense-mediated RNA decay pathway. UPF3A levels are tightly regulated in cells by its destabilization via UPF3B-dependent mechanism. UPF3A forms a complex with RNA-binding protein 8A (Y14), protein mago nashi homolog (MAGOH), eukaryotic initiation factor 4A-III (eIF4AIII) and barentsz (BTZ). Together the complex is required for NMD pathway. UPF3A interacts specifically with spliced mRNAs. It is also a component of exon-exon junction complex and is important for translation efficiency.

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.
