A number of ELISA Kits are available that target Ubiquitin Conjugating Enzyme E2I, an alias of the protein, ubiquitin conjugating enzyme E2 I. The human protein, encoded by the gene UBE2I, is an enzyme and member of the Ubiquitin-conjugating enzyme family. The protein's cellular localization is indicated to be cytoplasmic and nuclear. Additional synonyms or past names for this protein may include: C358B7.1, P18, UBC9. Homology is conserved in other species, such as Mouse, Rat, Fly, Yeast, Arabidopsis, Zebrafish, Frog.
