Previous GeneCards Identifiers for PSMD12 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. A pseudogene has been identified on chromosome 3. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2015]
GeneCards Summary for PSMD12 Gene
PSMD12 (Proteasome 26S Subunit, Non-ATPase 12) is a Protein Coding gene. Diseases associated with PSMD12 include Stankiewicz-Isidor Syndrome and Non-Specific Syndromic Intellectual Disability. Among its related pathways are Downstream signaling events of B Cell Receptor (BCR) and CDK-mediated phosphorylation and removal of Cdc6. An important paralog of this gene is COPS4.
UniProtKB/Swiss-Prot Summary for PSMD12 Gene
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.
