Synonyms
Proteasome (prosome, macropain) subunit beta type 3, Proteasome chain 13, HC10-II, Proteasome component C10-II, Proteasome theta chain, EC 3.4.25.1, MGC4147.
Introduction
The proteasome is a multicatalytic proteinase complex with an extremely organized ring-shaped 20S core structure. The core structure consists of 4 rings of 28 non-identical subunits; 2 rings consist of 7 alpha subunits and 2 rings consist of 7 beta subunits. Proteasomes are spread all over the eukaryotic cells in large quantities and cleave peptides in an ATP/ubiquitin-dependent procedure in a non-lysosomal pathway. A vital role of a modified proteasome, the immunoproteasome, is the handling of class I MHC peptides.
Description
