Ubiquitin Conjugating Enzyme E2Q Like Protein 1 (UBE2QL1)

UBE2QL1 belongs to the ubiquitin-conjugating enzyme family. Ubiquitin-conjugating enzymes, also known as E2 enzymes and more rarely as ubiquitin-carrier enzymes, perform the second step in the ubiquitination reaction that targets a protein for degradation via the proteasome.The ubiquitination process covalently attaches ubiquitin, a short protein of 76 amino acids, 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 proteasome"""s 19S regulatory particle, triggering the ATP-dependent unfolding of the target protein that allows passage into the proteasome"""s 20S core particle, where proteases degrade the target into short peptide fragments for recycling by the cell.
