UB212: UBE2E2




UBE2E2 is an E2 conjugation enzyme that is involved in the ubiquitylation of target substrates, along with E1 and E3 enzymes. It is a protein that in humans is encoded by the UBE2E2gene. Amino acid sequence within the UBC domain of UBE2E2 shares over 90% identity with human UbcH6, mouse UbcM2, and Drosophila UbcD2, whereas the N-terminal region shows little amino acid sequence similarity with known proteins. UBE2E2 forms a thioester bond with ubiquitin in an E1-dependent manner and mediates the transfer of ubiquitin from a ubiquitin-activating enzyme (E1) to a substrate protein or E3 ligase.
