The 26S proteasome consists of a 20S proteasome core and two 19S regulatory subunits (PubMed:25599644, 26133119, 26657688, 27342858, 27428775, 27493187, 34711951). The 20S proteasome core is a barrel-shaped complex made of 28 subunits that are arranged in four stacked rings (PubMed:25599644, 26133119, 26657688, 27342858, 27428775, 27493187, 34711951). The two outer rings are each formed by seven alpha subunits, and the two inner rings are formed by seven beta subunits (PubMed:25599644, 26133119, 26657688, 27342858, 27428775, 27493187, 34711951). The proteolytic activity is exerted by three beta-subunits PSMB5, PSMB6 and PSMB7 (PubMed:25599644, 26133119, 26657688, 27342858, 27428775, 27493187, 34711951). Interacts with AURKB (PubMed:14674694). Interacts with CDKN1A (PubMed:11350925). Interacts with MDM2 and RB1 (PubMed:16337594). Interacts with the C-terminus of TBXA2R isoform 2 (PubMed:17499743). Interacts with DNAJB2 (PubMed:15936278). (Microbial infection) Interacts with HIV-1 Tat protein. (Microbial infection) Interacts with hepatitis C virus (HCV) F protein. (Microbial infection) Interacts with Epstein-Barr virus EBNA3 proteins.
