Protein Name: Proteasome subunit beta type-5

UniprotKB/SwissProt ID: PSB5_MOUSE (O55234)

Gene Name: Psmb5

Organism: Mus musculus (Mouse).

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. This unit is responsible of the chymotrypsin-like activity of the proteasome and is one of the principal target of the proteasome inhibitor bortezomib (By similarity). Plays a role in the protection against oxidative damage through the Nrf2-ARE pathway.
