Supplementary information

Proteasome 19S S4 also known as PSMC1 is a mechanical component of the 26S proteasome an ATP-dependent protease complex responsible for protein degradation. This protein functions as an ATPase and contributes to the unfolding of ubiquitinated proteins preparing them for translocation into the 20S core particle of the proteasome for degradation. S4/PSMC1 has a molecular mass of approximately 49 kDa and is expressed ubiquitously across various cell types reflecting its essential role in cellular protein homeostasis.
Biological function summary

PSMC1 functions as an integral part of the 19S regulatory particle of the 26S proteasome complex. This complex facilitates the recognition unfolding and translocation of polyubiquitinated proteins into the proteolytic chamber of the 20S core particle for degradation. This activity plays a significant role in regulating intracellular protein concentrations thereby controlling processes like cell cycle progression apoptosis and responses to oxidative stress. PSMC1’s activity ensures a clean cellular environment by removing damaged or nonfunctional proteins.

Pathways

Functions of PSMC1 integrate into the ubiquitin-proteasome pathway and the cell cycle control pathway. In the ubiquitin-proteasome pathway PSMC1 collaborates with other ATPase subunits and regulatory proteins helping to maintain protein degradation balance and works closely with ubiquitin-conjugating enzymes responsible for tagging proteins for degradation. In the cell cycle control pathway the degradation of cyclins and cyclin-dependent kinase inhibitors by the proteasome including PSMC1 regulates cell cycle transitions and ensures proper cell division and function.

Alterations in PSMC1 function or expression can link to disorders such as cancer and neurodegenerative diseases. In cancer the dysregulation of PSMC1 can affect cellular proliferation by disrupting regulated protein degradation leading to uncontrolled cell growth. In neurodegenerative diseases such as Parkinson's impaired proteasome function including the activity of PSMC1 may lead to the accumulation of misfolded proteins contributing to neuronal cell death. Connections to other proteins like cyclins in cancer or alpha-synuclein in Parkinson's enhance the consequences of dysfunctional PSMC1 activity in these diseases.

Target data

Component of the 26S proteasome, a multiprotein complex involved in the ATP-dependent degradation of ubiquitinated proteins. This complex plays a key role in the maintenance of protein homeostasis by removing misfolded or damaged proteins, which could impair cellular functions, and by removing proteins whose functions are no longer required. Therefore, the proteasome participates in numerous cellular processes, including cell cycle progression, apoptosis, or DNA damage repair. PSMC1 belongs to the heterohexameric ring of AAA (ATPases associated with diverse cellular activities) proteins that unfolds ubiquitinated target proteins that are concurrently translocated into a proteolytic chamber and degraded into peptides.
