Western blot - Human PTGES3 (p23) knockout HEK-293T cell line (AB266791)

Lanes 1-4 : Merged signal (red and green). Green - ab92503 observed at 23 kDa. Red - loading control ab8245 observed at 36 kDa.

ab92503 Anti-p23 antibody [EPR3846] was shown to specifically react with p23 in wild-type HEK-293T cells. Loss of signal was observed when knockout cell line ab266791 (knockout cell lysate ab258151) was used. Wild-type and p23 knockout samples were subjected to SDS-PAGE. ab92503 and Anti-GAPDH antibody [6C5] - Loading Control (ab8245) were incubated overnight at 4° at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.

Handling procedures

Initial handling guidelines

Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.

1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.

Subculture guidelines
  • All seeding densities should be based on cell counts gained by established methods.
  • A guide seeding density of 2x104 cells/cm2 is recommended.
  • Cells should be passaged when they have achieved 80-90% confluence.
Culture medium

DMEM (High Glucose) + 10% FBS

Supplementary information

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

The p23 protein also known as prostaglandin E synthase 3 weighs about 18 kDa. It functions as a co-chaperone for the heat shock protein 90 (Hsp90) complex. P23 is found in the cytoplasm and nucleus of cells and shows expression across various tissues including the brain liver and kidney. It plays a role in stabilizing the ATP-bound state of Hsp90 assisting in client protein stabilization and maturation. P23 binding to the Hsp90 complex influences its chaperone activity.
Biological function summary

P23 assists Hsp90 in protein-folding processes. As part of the Hsp90 chaperone complex p23 contributes to the correct folding and functioning of several essential client proteins. This chaperone activity is important for cellular processes like signal transduction and protein degradation. Without p23 Hsp90's efficiency in maintaining protein homeostasis can decrease highlighting the importance of their interaction in the cell.

Pathways

The chaperone actions of p23 extensively impact protein signaling pathways and stress response mechanisms. P23 and Hsp90 are important in the Akt/PI3K signaling pathway which regulates cell proliferation and survival. The complex formed by p23 and Hsp90 also involves heat shock proteins like Hsp70 which collaborates in broader cellular stress responses. These connections demonstrate how p23 integrates into cellular regulation and signal transduction networks.

P23's interaction with Hsp90 relates to cancer development and progression. Dysregulation in the p23-Hsp90 interaction can lead to increased stabilization of oncogenic client proteins contributing to tumorigenesis. Additionally p23 implication has been noted in neurodegenerative diseases like Alzheimer's where protein misfolding plays a critical role. Here p23 involvement with proteins like Tau may link its chaperone activity to the pathological protein aggregation seen in such disorders.
