PSMB11 encodes the human gene, Proteasome (prosome, macropain) subunit, beta type, 11. It may also be known as: Proteasome subunit beta type-11; Proteasome subunit beta type-11 ; Proteasome subunit beta-5t; BETA5T. The encoded protein is an enzyme with an amino acid length of 300 and a mass of 32.5 kDa. PSMB11 is a member of the Peptidase T1B family. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog.
