  • 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 trypsin-like activity.
  • Tissue specificity

    Expressed at a low level in colonic mucosa. Up-regulated in colorectal cancer tissues.
  • Sequence similarities

    Belongs to the peptidase T1B family.
  • Cellular localization

    Cytoplasm. Nucleus.
