Anti-UBE2S antibodies are used in the immunodetection of the protein ubiquitin conjugating enzyme E2 S. In humans, the canonical protein has a reported length of 222 amino acid residues and a mass of 23.8 kDa. It is notably expressed in the vagina, tonsil, testis, lymph node, and appendix. A member of the Ubiquitin-conjugating enzyme protein family, UBE2S is known to accept ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. Post-translational modifications have been described, including ubiquitination. Synonyms for this target antigen include E2EPF, EPF5, E2 ubiquitin-conjugating enzyme S, E2-EPF5, ubiquitin carrier protein S, and E2-EPF. UBE2S gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of UBE2S antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Flow Cytometry, Immunofluorescence, and Immunohistochemistry are also common applications.
