UniProtKB description: Interacts with the core proteasome alpha-subunit (PrcA) through its C-terminal hydrophobic-tyrosine-X motif (HbYX motif). Interaction of Bpa with the proteasome stimulates proteasomal peptidase and casein degradation activity, which suggests Bpa could play a role in the removal of non-native or damaged proteins by influencing the conformation of the proteasome complex upon interaction. Can inhibit degradation of Pup-tagged substrates in vitro by competing with Mpa for association with the proteasome.
