General description

Anti-Protein Disulfide Isomerase (PDI) (MD-12) is developed in rabbit using as immunogen a synthetic peptide corresponding to amino acid residues of human PDI with N-terminal added cysteine, conjugated to KLH. 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. The mammalian PDI family comprises several highly divergent proteins that contain one or more thioredoxin like structural domains. PDI consists of four tandem domains, two of which contain a catalytic site for S-S bond formation. PDI has an N-terminal ER signal and C-terminal ER retention KDEL signal sequences. PDI may also be expressed in other cellular localizations such as the cell surface, cytosol, and nucleus. PDI was found on the cell surface of several cell types including platelets, lymphoid cells, pancreatic exocrine cells, retinal cells, thyroid cells, and hepatocytes.

Immunogen

synthetic peptide corresponding to amino acid residues 495-506 of human protein disulfide isomerase.

Application

Anti-Protein Disulfide Isomerase (MD-12) antibody produced in rabbit has been used in:
  • immunoblotting
  • immunoprecipitation
  • immunofluorescence

Biochem/physiol Actions

Protein disulfide isomerase (PDI) catalyses the formation and rearrangements of both intrachain and interchain disulfide bonds in secreted proteins. PDI also serves as a molecular chaperone that can suppress protein aggregation, or as an anti-chaperone that mediates aggregate formation. PDI respectively participates in the hydroxylation of prolines in procollagen during collagen synthesis and in the transfer of neutral lipid onto nascent lipoprotein particles. PDI has calcium-dependent transglutaminase activity, which catalyses the formation of isopeptide bonds.

Physical form

Solution in 0.01 M phosphate buffered saline containing 1% bovine serum abumin and 15 mM sodium azide.

Ferroptosis is a form of regulated cell death resulting predominantly from catastrophic accumulation of lipid reactive oxygen species (ROS). While the antioxidant systems that counter ferroptosis have been well characterized, the mechanism underlying ferroptosis-associated accumulation of lipid ROS remains unclear.
