    • Function

      This multifunctional protein catalyzes the formation, breakage and rearrangement of disulfide bonds. At the cell surface, seems to act as a reductase that cleaves disulfide bonds of proteins attached to the cell. May therefore cause structural modifications of exofacial proteins. Inside the cell, seems to form/rearrange disulfide bonds of nascent proteins. At high concentrations, functions as a chaperone that inhibits aggregation of misfolded proteins. At low concentrations, facilitates aggregation (anti-chaperone activity). May be involved with other chaperones in the structural modification of the TG precursor in hormone biogenesis. Also acts a structural subunit of various enzymes such as prolyl 4-hydroxylase and microsomal triacylglycerol transfer protein MTTP.
    • Sequence similarities

      Belongs to the protein disulfide isomerase family.
      Contains 2 thioredoxin domains.
    • Cellular localization

      Endoplasmic reticulum lumen. Melanosome. Cell membrane. Highly abundant. In some cell types, seems to be also secreted or associated with the plasma membrane, where it undergoes constant shedding and replacement from intracellular sources (Probable). Localizes near CD4-enriched regions on lymphoid cell surfaces. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.

      Lanes 1 - 3: Merged signal (red and green). Green - ab137119 observed at 57 kDa. Red - loading control, ab9484, observed at 37 kDa.

      ab137119 was shown to specifically react with P4HB (Protein disulfide-isomerase) in wild-type HeLa cells as signal was lost in P4HB knockout cells. Wild-type and P4HB knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% milk. Ab137119 and ab9484 (Mouse anti-GAPDH loading control) were incubated overnight at 4°C at 1 μg/ml and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
