Jamming the Proteasome (IMAGE) California Institute of Technology Caption A dysfunctional protein (green) gets tagged for destruction with a ubiquitin chain (gray). Ubiquitin guides the bad protein to the proteasome for destruction, and is snipped off--a process called deubiquitination. A new cancer treatment would inhibit this vital part of the process, causing cancer cells to fill up with dysfunctional proteins and self-destruct.
