PDIR Antibody (B-9) is a mouse monoclonal IgG2a kappa light chain antibody that detects PDIR protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), and enzyme-linked immunosorbent assay (ELISA). PDIR Antibody (B-9) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. PDIR protein, also known as Protein disulfide isomerase-related protein or PDIA5, is a crucial 519 amino acid protein localized in the lumen of the endoplasmic reticulum (ER), where PDIA5 plays a vital role in the oxidative refolding of proteins. PDIA5 is essential for the proper folding and maturation of secretory and membrane proteins, as PDIA5 catalyzes the rearrangement of disulfide bonds, which is critical for maintaining protein structure and function. PDIR′s unique structure includes one ER retention signal at its C-terminus and three thioredoxin motifs, which are integral to PDIR′s substrate-specific isomerase, chaperone, and redox activities. By facilitating the formation of disulfide bonds, PDIR not only ensures the stability of proteins like α1-antitrypsin but also contributes to the overall protein quality control within the ER, making PDIR a key player in cellular homeostasis and response to stress.
