Anti-UPK3A antibody produced in rabbit

The gene uroplakin-3a (UPK3A) is mapped to human chromosome 22q. It is a transmembrane protein and is present at the apical membrane of superficial umbrella cells of urothelium.

Uroplakin-3A Precursor recombinant protein epitope signature tag (PrEST)

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.

Uroplakin-3a (UPK3A) forms heterodimer with another member of the same family, UPK1B. Absence of UPK3A in mouse model causes abnormal targeting of UPK1B. In addition, absence of UPK3A in urothelium causes formation of small plaques, leakiness and results in hydronephrosis. UPK3A is involved in uropathogenic Escherichia coli invasion. It interacts with the bacterial type-1 pilus adhesion, FimH, and undergoes phosphorylation with subsequent elevation of intracellular calcium. These signaling events are crucial for bacterial invasion and urothelial apoptosis. UPK3A is associated with urothelial carcinoma, carcinoma metastatic to the bladder. UPK3A is up-regulated in vesicoureteral reflux, a common congenital urinary tract anomaly.

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.
