As stated in the paper of Peters, et al., 1994: "Proteasomes are very large protein complexes found in some of the living organisms" [1].

Proteasomes have a key essential role in the cell by controling the protein and degrading the amino acids creating new proteins [2].

In addition, proteasome controls cell-cycle progression and apoptosis which act as crutial target in anti-cancer therapy[3].
