Gene

• Entrez ID: 5708
• Gene name: Proteasome 26S subunit ubiquitin receptor, non-ATPase 2
• Gene symbol: PSMD2
• Synonyms (NCBI Gene): P97, RPN1, S2, TRAP2
• Chromosome: 3
• Chromosome location: 3q27.1
• Summary: 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 a
