ab2792 staining P4HB in wild-type A431 cells (top panel) and P4HB knockout A431 cells (bottom panel). The cells were fixed with 100% methanol (5 min), permeabilized with 0.1% PBS-Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated overnight at 4°C with ab2792 at 1µg/ml and ab6046, Rabbit polyclonal to beta Tubulin - Loading Control. Cells were then incubated with ab150117, Goat polyclonal Secondary Antibody to Mouse IgG H&L (Alexa Fluor® 488) preadsorbed at 1/1000 dilution (shown in green) and ab150084, Goat Anti-Rabbit IgG H&L (Alexa Fluor® 594) preadsorbed at 1/1000 dilution (shown in pseudocolour red). Nuclear DNA was labelled with DAPI (shown in blue). Also suitable in cells fixed with 4% paraformaldehyde (10 min). Image was acquired with a high-content analyser (Operetta CLS, Perkin Elmer) and a maximum intensity projection of confocal sections is shown.

The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab2792, 0.5μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 1μg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

Immunohistochemistry was performed on both normal and cancer biopsies of deparaffinized Human tonsil tissue tissues. To expose target proteins heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1 : 200 with a mouse monoclonal antibody recognizing P4HB (PDIA1) ab2792 or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.

Western blot analysis of P4HB (PDIA1) was performed by loading 25 ug of HepG2 (Lane 1) Hela (Lane 2) and NIH-3T3 (Lane 3) cell lysates onto an SDS polyacrylamide gel. Proteins were transferred to a PVDF membrane and blocked at 4°C overnight. The membrane was probed with ab2792 at 1 : 1000 overnight at 4°C and washed in TBST. The membrane was then probed with a HRP-conjugated secondary antibody for 1 hr at room temperature in the dark. Chemiluminescent detection was performed using a ECL Plus Western Blotting Substrate. Results show a band at approx. 57 kDa.

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

P4HB is a protein known as Protein Disulfide Isomerase (PDI). It plays a significant role in catalyzing the formation of disulfide bonds. This protein helps to fold newly synthesized proteins by shuffling disulfide bonds. It has a molecular mass of around 57 kDa. P4HB is mainly expressed in the endoplasmic reticulum of cells. While its alternative name is ERp59 P4HB is integral to the protein folding machinery inside cells.
Biological function summary

P4HB functions in protein folding and assembly. By acting as a chaperone it protects proteins from misfolding and aggregation. P4HB operates as part of a larger multi-protein complex that assists in maintaining protein structure under stress conditions in the cell. Its activity ensures protein stability and proper cellular function important for cell viability and health.

Pathways

P4HB plays a central role in the unfolded protein response (UPR) and oxidative protein folding pathway. It interacts with proteins such as calnexin and calreticulin through its involvement in these pathways. During oxidative protein folding P4HB introduces disulfide bonds into nascent proteins while removing incorrect ones ensuring efficient protein quality control.

P4HB alteration has connections to diseases like cancer and neurodegenerative disorders. Its overexpression and activity can promote tumor growth by aiding cancerous cell survival through protein homeostasis. Moreover P4HB's association with amyloid precursor protein impacts the progression of Alzheimer's disease. These connections make P4HB a relevant target for research into therapeutic interventions.

Target data

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 and following phosphorylation by FAM20C, functions as a chaperone that inhibits aggregation of misfolded proteins (PubMed : 32149426). 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 as 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 (PubMed : 21670307).
