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:Q99460}.
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 and few additional
CC components including PSMD1. Interacts with ADRM1. Interacts with ZFAND1
CC (By similarity). {ECO:0000250|UniProtKB:Q99460}.
CC -!- SIMILARITY: Belongs to the proteasome subunit S1 family. {ECO:0000305}.
