Anti-ATP6V1H antibody produced in rabbit

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.

The gene ATP6V1H (ATPase H⁺ transporting V₁ subunit H) encodes the regulatory subunit H of the V₁ domain of V-ATPase. This multisubunit complex of V-ATPase functions in the acidification of intracellular compartments via the energy generated from ATP hydrolysis. Therefore, V-ATPase participates in receptor-mediated endocytosis, intracellular trafficking processes and degradation of proteins. Down-regulation of ATP6V1H gene in human pancreatic islets has been associated with type 2 diabetes. Its expression is negatively associated with HbA1c levels. It has a positive regulatory effect on glucose-stimulated insulin secretion.

Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.

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.

The gene ATP6V1H (ATPase H+ transporting V1 subunit H) is mapped to human chromosome 8q11.2. It encodes a lysosomal protein with a molar mass of 50/57kDa. This protein forms the subunit of vacuolar ATPase (V-ATPase), a protein widely found in various eukaryotic endomembrane organelles. V-ATPase is a member of the rotary ATPase family, the members of which use rotary motor mechanisms for the transportation of ions across membranes. V-ATPase has two domains, V₀ and V₁ that function in transportation of proton and hydrolysis of ATP, respectively. The V₁ domain is composed of eight subunits, A-H.
