CC -!- FUNCTION: Component of the 26S proteasome, a multiprotein complex
CC involved in the ATP-dependent degradation of ubiquitinated proteins.
CC This complex plays a key role in the maintenance of protein homeostasis
CC by removing misfolded or damaged proteins, which could impair cellular
CC functions, and by removing proteins whose functions are no longer
CC required. Therefore, the proteasome participates in numerous cellular
CC processes, including cell cycle progression, apoptosis, or DNA damage
CC repair. PSMC4 belongs to the heterohexameric ring of AAA (ATPases
CC associated with diverse cellular activities) proteins that unfolds
CC ubiquitinated target proteins that are concurrently translocated into a
CC proteolytic chamber and degraded into peptides.
CC {ECO:0000256|ARBA:ARBA00002699}.
CC -!- SIMILARITY: Belongs to the AAA ATPase family.
CC {ECO:0000256|ARBA:ARBA00006914, ECO:0000256|RuleBase:RU003651}.
