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. {ECO:0000250|UniProtKB:O00232}.
CC   -!- SUBUNIT: Component of the 19S proteasome regulatory particle complex
CC       (By similarity). The 26S proteasome consists of a 20S core particle
CC       (CP) and two 19S regulatory subunits (RP) (By similarity). The
CC       regulatory particle is made of a lid composed of 9 subunits including
CC       PSMD12, a base containing 6 ATPases and few additional components (By
CC       similarity). Interacts with ERCC6 (By similarity).
CC       {ECO:0000250|UniProtKB:O00232}.
CC   -!- SIMILARITY: Belongs to the proteasome subunit p55 family.
CC       {ECO:0000305}.
