Previous GeneCards Identifiers 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]

PSMD9 (Proteasome 26S Subunit, Non-ATPase 9) is a Protein Coding gene. Diseases associated with PSMD9 include Carpal Tunnel Syndrome and Generalized Anxiety Disorder. Among its related pathways are Regulation of activated PAK-2p34 by proteasome mediated degradation and Antigen processing-Cross presentation. Gene Ontology (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 Summary 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.
