Target Information

Protein disulfide isomerase (PDI) is a multifunctional protein that catalyzes the formation, breakage, and rearrangement of disulfide bonds.
At the cell surface, PDI acts as a reductase that cleaves disulfide bonds of proteins attached to the cell, potentially causing structural modifications of exofacial proteins.
Inside the cell, PDI forms and rearranges disulfide bonds of nascent proteins.
At high concentrations, it functions as a chaperone that inhibits aggregation of misfolded proteins, while at low concentrations, it facilitates aggregation (anti-chaperone activity).
PDI may also participate with other chaperones in the structural modification of the thyroglobulin precursor during hormone biogenesis and acts as a structural subunit of enzymes such as prolyl 4-hydroxylase and microsomal triacylglycerol transfer protein (MTTP).
It serves as a receptor for LGALS9, retaining P4HB at the cell surface of Th2 T helper cells, enhancing disulfide reductase activity at the plasma membrane, altering the redox state, and promoting cell migration.
