PDI Antibody (PA5-77821) in WB
Western blot was performed using Anti-PDI Polyclonal Antibody (Product # PA5-77821) and a 57 kDa band corresponding to PDI was observed across the cell lines and tissues tested. Membrane enriched extracts (30 µg lysate) of Hep G2 (Lane 1), HeLa (Lane2), NIH/3T3 (Lane 3), A-375 (Lane 4), A-431 (Lane 5), HEK-293 (Lane 6), and tissue extracts of Mouse Liver (Lane 7), Rat Liver (lane 8) and Rat Testis (Lane 9) were electrophoresed using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0322BOX). Resolved proteins were then transferred onto a nit... View More

Target Information
Protein disulfide isomerase (PDI) is a multifunctional protein that catalyzes the formation, breakage and rearrangement of disulfide bonds. At the cell surface, the protein seems to act as a reductase that cleaves disulfide bonds of proteins attached to the cell. It may therefore cause structural modifications of exofacial proteins. Inside the cell, PDI seems to form/rearrange disulfide bonds of nascent proteins. At high concentrations, it functions as a chaperone that inhibits aggregation of misfolded proteins. At low concentrations, it facilitates aggregation (anti-chaperone activity). PDI may be involved with other chaperones in the structural modification of the TG precursor in hormone biogenesis. It also acts a structural subunit of various enzymes such as prolyl 4-hydroxylase and microsomal triacylglycerol transfer protein MTTP. Receptor for LGALS9; the interaction retains P4HB at the cell surface of Th2 T helper cells, increasing disulfide reductase activity at the plasma membrane, altering the plasma membrane redox state and enhancing cell migration.
