General annotation (Comments)
| Function | The proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity. Mediates the lipopolysaccharide-induced signal macrophage proteasome By similarity. SMAD1/OAZ1/PSMB4 complex mediates the degradation of the CREBBP/EP300 repressor SNIP1. Ref.15 |
| Catalytic activity | Cleavage of peptide bonds with very broad specificity. |
| Subunit structure | The 26S proteasome consists of a 20S proteasome core and two 19S regulatory subunits. The 20S proteasome core is composed of 28 subunits that are arranged in four stacked rings, resulting in a barrel-shaped structure. The two end rings are each formed by seven alpha subunits, and the two central rings are each formed by seven beta subunits. The catalytic chamber with the active sites is on the inside of the barrel. Interacts with HIV-1 TAT and HIV-1 NEF proteins. Interaction with HTLV-1 TAX protein favors NFKB1 activation. Interacts with bacterial lipopolysaccharide (LPS) By similarity. Forms a ternary complex with SMAD1 and OAZ1 before PSMB4 is incorporated into the 20S proteasome. Interacts with PRPF19. Ref.12 Ref.13 Ref.14 Ref.15 Ref.16 Ref.17 |
| Subcellular location | |
| Induction | Up-regulated in fibrolamellar carcinomas. Ref.20 |
| Sequence similarities | Belongs to the peptidase T1B family. |
