General description
The gene prolyl 4-hydroxylase subunit β (P4HB) is mapped to human chromosome 17q25. It belongs to the family of soluble oxidoreductases. The protein is present at the cell surface of B cells, platelets, pancreatic cells and hepatocytes. The protein localizes in the endoplasmic reticulum and at the cell surface. P4HB is also called as PDI (protein disulfide isomerase).

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
Prolyl 4-hydroxylase subunit β (P4HB) is involved in the formation of disulfide bonds. In addition, it binds polypeptide chains and work as a chaperone, thereby helping in folding of polypeptides. It also works as a subunit of prolyl 4-hydroxylase (P4H). Impairment in disulfide isomerase activity of P4HB is associated with Cole-Carpenter syndrome. Single nucleotide polymorphism in P4HB is associated with amyotrophic lateral sclerosis. P4HB is up-regulated in presence of hypoxia in astrocytes. It works together with ubiquilin in protecting neurons against apoptosis.
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.

Up-regulation of several stress proteins such as heat-shock proteins and glucose-regulated proteins participate in tolerance against environmental stress. Previously, we found that protein-disulfide isomerase (PDI) is specifically up-regulated in response to hypoxia/brain ischemia in astrocytes. In addition, the overexpression of
