Proteasomal ubiquitin receptor ADRM1

UniProtKB accession:  Q9JKV1

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Component of the 26S proteasome, a multiprotein complex involved in the ATP-dependent degradation of ubiquitinated proteins (PubMed:18497827). 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 (PubMed:18497827). Therefore, the proteasome participates in numerous cellular processes, including cell cycle progression, apoptosis, or DNA damage repair (PubMed:18497827). Within the complex, functions as a proteasomal ubiquitin receptor (PubMed:18497827). Engages and thus activates 19S-associated deubiquitinases UCHL5 and PSMD14 during protein degradation (By similarity). UCHL5 reversibly associate with the 19S regulatory particle whereas PSMD14 is an intrinsic subunit of the proteasome lid subcomplex (By similarity).
