Other Information

**Key Characteristics:** PSMD9 is a non-ATPase regulatory subunit of the 26S proteasome, a large protein complex responsible for degrading damaged or unneeded proteins. The 26S proteasome is a critical component of the ubiquitin-proteasome pathway (UPP), which regulates protein turnover and cell signaling. PSMD9 is specifically involved in the regulation of protein degradation, cell cycle progression, and immune responses. **Pathways and Functions:** PSMD9 is involved in various cellular pathways, including: 1. **Adaptive Immune System:** PSMD9 regulates the activation and proliferation of T cells, a crucial step in the adaptive immune response. 2. **Antigen Processing-Cross Presentation:** PSMD9 is involved in the processing and presentation of antigens to T cells, a process essential for initiating an immune response. 3. **Apoptosis:** PSMD9 regulates the degradation of pro-apoptotic proteins, influencing cell survival and death. 4. **Cell Cycle:** PSMD9 is involved in the regulation of cell cycle progression, particularly in the G1/S and G2/M phases. 5. **Immune System:** PSMD9 is expressed in various immune cells, including monocytes, T cells, and dendritic cells, and plays a role in the regulation of immune responses. **Clinical Significance:** Dysregulation of PSMD9 has been implicated in various diseases, including: 1. **Autoimmune Disorders:** Abnormalities in PSMD9 expression and function have been linked to autoimmune diseases, such as rheumatoid arthritis and lupus. 2. **Cancer:** PSMD9 is overexpressed in certain types of cancer, including breast and lung cancer, and is associated with tumor progression and metastasis. 3. **Infectious Diseases:** PSMD9 is involved in the regulation of immune responses to viral infections, such as HIV and influenza. 4. **Neurological Disorders:** PSMD9 is implicated in the pathogenesis of neurodegenerative diseases, such as Alzheimer's and Parkinson's. In conclusion, PSMD9 plays a critical role in regulating various cellular processes, including immune responses, cell cycle, and apoptosis. Dysregulation of PSMD9 has been implicated in various diseases, highlighting the importance of further research into its mechanisms and potential therapeutic applications.
