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
- Cryopreservation medium
- Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.

- Activity summary
Proteasome Activator Subunit 4 (PSME4) also known as PA200 is an important component in regulating protein degradation. It belongs to the family of proteasome activator subunits and has a molecular mass of approximately 230 kDa. PSME4 is mainly expressed in the nucleus of cells and modulates proteasome activity by binding to the proteasome core particle. Through facilitating protein breakdown PSME4 significantly influences various cellular processes including the elimination of oxidatively damaged proteins.
- Biological function summary
PSME4 functions as part of a complex that enhances proteasome-mediated protein degradation. This complex formation improves the efficiency of protein processing by recruiting specific substrates for degradation. PSME4 is involved in DNA repair processes and plays a role in spermatogenesis contributing to proper cell cycle progression and genomic stability. The protein's activity in these biological functions demonstrates its importance in maintaining cellular homeostasis.
- Pathways
PSME4 is intricately involved in the ubiquitin-proteasome pathway and the DNA damage response pathway which are essential for maintaining protein quality control and genomic integrity. PSME4 interacts with other proteins such as RAD23B facilitating the repair of damaged DNA. By integrating into these pathways PSME4 ensures the proper execution of critical cellular processes and responds to stress-related signals.
- Associated diseases and disorders
Alterations in PSME4 expression or function have connections to cancer progression and neurodegenerative diseases. In cancer PSME4 may influence tumor growth and resistance to therapy through its role in DNA repair and protein turnover. Additionally in neurodegenerative conditions like Alzheimer's disease PSME4-associated proteasome dysfunction contributes to the accumulation of toxic protein aggregates. Understanding PSME4 interactions with proteins like p53 in cancer or tau in neurodegeneration offers insights into potential therapeutic targets.
