Activity summary

Proteasome 20S beta 6 also known as PSMB6 is a subunit of the proteasome complex. It plays a significant role in the protein degradation process. Its molecular weight is around 25 kDa. The subunit gets expressed in various cell types throughout the body ensuring that proteins are effectively broken down into peptides. This is essential for maintaining protein homeostasis and recycling faulty proteins.

Biological function summary

The proteasome 20S beta 6 subunit forms part of the 20S core complex an important component of the proteasome. The proteasome operates as the main proteolytic machinery in both nucleus and cytoplasm. The 20S core complex pairs with the regulatory 19S cap to form the 26S proteasome. This assembly degrades ubiquitin-tagged proteins which regulates cell cycle progression apoptosis and DNA repair contributing to cellular function and health.

Pathways

Proteasome 20S beta 6 acts within the ubiquitin-proteasome pathway. This pathway regulates protein turnover affecting critical cellular processes such as cell cycle apoptosis and the immune response. The pathway also links with other proteins such as ubiquitin and E1 E2 and E3 ligases which modify proteins with ubiquitin chains to signal for their degradation.

Associated diseases and disorders

Proteasome 20S beta 6 may relate to cancer and neurodegenerative diseases like Alzheimer's. The abnormal regulation of the proteasome pathway can lead to the accumulation of undegraded proteins contributing to these diseases. PSMB6 interacts with proteins such as p53 a tumor suppressor protein highlighting its relevance to cell cycle control and cancer progression.
