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 17.
Applications:Suitable for use in Western Blot.
Other applications not tested.
Recommended Dilution:Optimal dilutions to be determined by the researcher.
