NCIt definition : 26S proteasome non-ATPase regulatory subunit 10 (226 aa, 24 kDa) is encoded by the
human PSMD10 gene. This protein is involved in both the assembly of the 26S proteasome,
ubiquitin-dependent protein degradation and signaling pathway regulation.;
NCIt note : 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. This protein is a non-ATPase subunit of the 19S regulator.
Proteasomes are distributed throughout eukaryotic cells at a high concentration and
cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway.
