In animal cells there are several regulatory complexes which interact with 20S proteasomes and give rise to functionally distinct proteasome complexes. gamma-Interferon upregulates three immuno beta catalytic subunits of the 20S proteasome and the PA28 regulator, and decreases the level of 26S proteasomes. It also decreases the level of phosphorylation of(More)
Proteasomes play a major role in non-lysosomal proteolysis and also in the processing of proteins for presentation by the MHC class I pathway. In animal cells they exist in several distinct molecular forms which contribute to the different functions. 26S proteasomes contain the core 20S proteasome together with two 19S regulatory complexes.
