Anti-KCNE4 antibody produced in rabbit

HPA011420    Human Protein Atlas characterization data

Potassium voltage-gated channel subfamily E member 4 recombinant protein epitope signature tag (PrEST)

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.

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.

KCNE4 (Potassium voltage-gated channel, Isk-related family, member 4) KCNE4, a membrane protein, is a member of single transmembrane domain protein family. It is a potential inhibitor of voltage-dependent potassium channels (Kv), which are essential for leukocyte activation and proliferation. It mainly inhibits the Kv trafficking, targeting and their functionality by altering certain activities including slowing down current density and activation rate, accelerating inactivation and cumulative inactivation etc. In endoplasmic reticulum, it conjugates with Kv1.3 and finally suppresses the Kv1.3 channels at the cell surface, resulting in less cell excitability. The association of KCNE4 with allergic rhinitis has been reported in the studies.

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.

Corresponding Antigen APREST72067.
