General description
Prolyl 4-hydroxylase subunit β (P4HB) or protein disulfide isomerase is a redox-regulated thiol-containing protein. The gene encoding this protein is localized on human chromosome 17q25.3.
Protein Disulfide Isomerase (PDI, Erp58) is an abundant multifunctional, soluble enzyme (E.C. 5.3.4.1) that resides in the lumen of the endoplasmic reticulum of eukaryotic cells. It consists of four tandem domains, two of which contain a catalytic site for disulfide bond formation. A mitochondrial isoform of PDI (approx. 54 kDa) has been recently described. PDI has an N-terminal endoplasmic reticulum (ER) signal and a C-terminal ER- retention KDEL signal sequences. PDI was found on the cell surface of several cell types including endothelial cells, platelets and hepatocytes.

Application
Anti-Protein Disulfide Isomerase antibody produced in rabbit has been used in immunoblotting, immunoprecipitation and immunofluorescence.
Biochem/physiol Actions
Prolyl 4-hydroxylase subunit β (P4HB) or protein disulfide isomerase acts as a molecular chaperone in the endoplasmic reticulum of cells and also as an oxidoreductase. It associates with steroid hormones and modulates their actions, concentrations and storage. P4HB accelerates the formation of disulphide bonds in proteins and hence aids in their folding.
Protein Disulfide Isomerase (PDI) catalyzes the formation and rearrangements of both intrachain and interchain disulfide bonds in secreted proteins. It plays an important role in various cellular processes including cell adhesion. PDI has calcium-dependent transglutaminase activity and is involved in the catalysis of isopeptide bond formation. PDI participates in the hydroxylation of proline in procollagen during collagen synthesis and in the transfer of neutral lipid onto nascent lipoprotein particles. Estrogen binding by PDI has also been reported.
