Recombinant human UBE2O (ubiquitin-conjugating enzyme E2 O) is a protein of interest in ubiquitination research. As a member of the E2 ubiquitin-conjugating enzyme family, UBE2O facilitates the transfer of ubiquitin molecules to substrate proteins, marking them for proteasomal degradation or functional modification. Unlike typical E2 enzymes, UBE2O exhibits unique dual functionality—acting both as an E2 ubiquitin-conjugating enzyme and an E3 ubiquitin ligase—through its N-terminal UBA domain and C-terminal catalytic domain. This hybrid activity enables substrate recognition and direct ubiquitin transfer without requiring separate E3 ligases, making it a subject of mechanistic studies.
UBE2O plays roles in erythroid differentiation, cellular stress responses, and protein quality control. Its dysfunction has been implicated in hematological disorders and cancers, with overexpression observed in leukemia and solid tumors. Recombinant UBE2O, typically produced in Escherichia coli or mammalian expression systems, is essential for in vitro studies of its enzymatic kinetics, substrate interactions, and structural properties. Researchers utilize purified UBE2O to investigate atypical ubiquitination patterns, develop targeted inhibitors, and explore therapeutic strategies for diseases linked to ubiquitination pathway dysregulation. Recent studies also suggest its involvement in chromatin remodeling and DNA repair processes, expanding its potential research applications.
