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:0000250|UniProtKB:P43686}.
CC -!- SUBUNIT: Component of the 19S proteasome regulatory particle complex.
CC The 26S proteasome consists of a 20S core particle (CP) and two 19S
CC regulatory subunits (RP). The regulatory particle is made of a lid
CC composed of 9 subunits, a base containing 6 ATPases including PSMC4 and
CC few additional components. Interacts with NR1I3. Interacts with PAAF1.
CC Interacts with TRIM5. Interacts with ZFAND1 (By similarity).
CC {ECO:0000250|UniProtKB:P43686}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P43686}. Nucleus
CC {ECO:0000250|UniProtKB:P43686}.
CC -!- SIMILARITY: Belongs to the AAA ATPase family. {ECO:0000305}.
