Summaries for PSMD9 Gene

Entrez Gene Summary for PSMD9 Gene

  • The 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes, a 20S core and a 19S regulator. The 20S core is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. The 19S regulator is composed of a base, which contains 6 ATPase subunits and 2 non-ATPase subunits, and a lid, which contains up to 10 non-ATPase subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides. This gene encodes a non-ATPase subunit of the 19S regulator. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, May 2012]

GeneCards Summary for PSMD9 Gene

PSMD9 (Proteasome 26S Subunit, Non-ATPase 9) is a Protein Coding gene. Among its related pathways are Cell Cycle Checkpoints and Mitotic Metaphase and Anaphase. GO annotations related to this gene include transcription coactivator activity and bHLH transcription factor binding. An important paralog of this gene is ENSG00000256950.

UniProtKB/Swiss-Prot for PSMD9 Gene

  • Acts as a chaperone during the assembly of the 26S proteasome, specifically of the base subcomplex of the PA700/19S regulatory complex (RC). During the base subcomplex assembly is part of an intermediate PSMD9:PSMC6:PSMC3 module, also known as modulator trimer complex; PSMD9 is released during the further base assembly process.
