"The U box is a domain of ∼70 amino acids that is present in proteins from yeast to humans."[1]

"The prototype U box protein, yeast Ufd2, was identified as a ubiquitin chain assembly factor that cooperates with a ubiquitin-activating enzyme (E1), a ubiquitin-conjugating enzyme (E2), and a ubiquitin-protein ligase (E3) to catalyze ubiquitin chain formation on artificial substrates."[1]

"The UFD2 protein and its homologs in other eukaryotes share a conserved domain designated the ‘U box’."[2]

"The U box mediates the interaction of UFD2 with ubiquitin conjugated proteins [...] the U box is a derived version of the RING-finger domain that lacks the hallmark metal-chelating residues of the latter [5,6] but is likely to function similarly to the RING-finger in mediating ubiquitin-conjugation of protein substrates."[2]
