PSMD1

26S proteasome non-ATPase regulatory subunit 1 • UniProt accession Q99460

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

Component of the 19S proteasome regulatory particle complex. The 26S proteasome consists of a 20S core particle (CP) and two 19S regulatory subunits (RP). The regulatory particle is made of a lid composed of 9 subunits, a base containing 6 ATPases and few additional components including PSMD1 (PubMed:27342858, PubMed:27428775).

Interacts with ADRM1 (PubMed:16906146, PubMed:16990800). Interacts with ZFAND1 (PubMed:29804830)
