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
TAPBP (TAP binding protein) is a component of the TAP complex and it links TAP (transporter associated with antigen processing) with MHC class I molecules. It plays pivotal role in enhancing the peptide-TAP interaction. It helps to attach MHC class I molecules with peptides across the endoplasmic reticulum in MHC assembly. Down regulated expression of TAPBP has been postulated in the primary human oral squamous cell carcinoma. Its expression is upregulated by several inflammatory molecules such as eicosanoids. It has also been reported that TAPBP may play a role in the development of Aspirin-exacerbated respiratory disease (AERD).
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.

Tapasin is required for efficient peptide binding to transporter associated with antigen processing.
S Li et al.
The Journal of biological chemistry, 275(3), 1581-1586 (2000-01-15)
The transporter associated with antigen processing (TAP) binds peptides in its cytosolic part and subsequently translocates the peptides into the lumen of the endoplasmic reticulum (ER), where assembly of major histocompatibility complex (MHC) class I and peptide takes place. Tapasin

Aspirin-exacerbated respiratory disease (AERD) is characterized by the development of airway obstruction in asthmatic individuals following the ingestion of aspirin or other nonsteroidal anti-inflammatory drugs. TAPBP (TAP-binding protein, tapasin) is upregulated by eicosanoids, which act as potent inflammatory molecules in

MHC class I peptide loading complex defects are frequently observed in tumor cells which facilitate tumor cells escaping from immune surveillance. Tapasin plays an important role in the assembly of MHC class I molecules with peptides in the endoplasmic reticulum.

The most common inherited cause of vascular dementia and stroke, cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), is caused by mutations in NOTCH3. Post-translationally altered NOTCH3 accumulates in the vascular media of CADASIL arteries in areas of
