Gene Information

human ... VAPB(9217)

General description

Vesicle-associated membrane protein-associated protein B/C (VAPB) belongs to the VAP family. It contains three structural domains: the major sperm protein (MSP) domain, an amphipathic helical structure and a carboxy-terminal domain that acts as a membrane anchor. VAPB is localized in intracellular membranes of the endoplasmic reticulum and Golgi apparatus. The gene encoding this protein is located on chromosome 20q13.3.

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

Vesicle-associated membrane protein-associated protein B/C (VAPB) plays a role during endoplasmic reticulum (ER)-Golgi transport and secretion. It has been shown to act in the unfolded protein response which is activated whenever misfolded proteins accumulate in the ER. Mutations in the gene encoding VAPB are associated with amyotrophic lateral sclerosis and late-onset spinal muscular atrophy.

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:
  • 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.

Phosphoinositides have a pivotal role in the maturation of nascent phagosomes into microbicidal phagolysosomes. Following degradation of their contents, mature phagolysosomes undergo resolution, a process that remains largely uninvestigated. Here we studied the role of phosphoinositides in phagolysosome resolution. Phosphatidylinositol-4-phosphate
