UBE2E3 also known as Ubiquitin-conjugating enzyme E2 E3 is a member of the E2 ubiquitin- conjugating enzyme family. This enzyme is required for the destruction of mitotic cyclins and for cell cycle progression. The ubiquitination process covalently attaches ubiquitin, a short protein of 76aa, to a lysine residue on the target protein. Once a protein has been tagged with one ubiquitin molecule, additional rounds of ubiquitination form a polyubiquitin chain that is recognized by the proteasomes 19S regulatory particle, triggering the ATP-dependent unfolding of the target protein that allows passage into the proteasomes 20S core particle, where proteases degrade the target into short peptide fragments for recycling by the cell.
