Ubiquitin and the UPS. The ubiquitin proteasomal system (UPS) is a common method of regulation for many proteins in the cell. The modification is actually generated by E3 ubiquitin ligase, of which there are ~400-800 in the mammalian cell and the main source of specificity in the UPS (E2 ~40 and only 1 or 2 E1).biquitin is active as part of a complex of proteins. Other elements of the complex recognise the proteins to be degraded. These recognition or specificity proteins are responsible for targetting proteins for ubiquitination. They are called ubiquitin ligases.
