Ubiquitin

This is what the actual label looks like. It consists of a short polypeptide chain, a small protein that is so common in the cells of different organisms that it was early named ubiquitin, from the Latin ubique, ‘everywhere’. This protein is not broken down in the proteasome but can be used again and again.
