Ready-to-use ELISA kits are available for the detection of Ubiquitin Conjugating Enzyme E2N, an alias of the protein, ubiquitin conjugating enzyme E2 N. The official gene symbol is UBE2N. The protein, with a mass of 17.1 kDa and length of 152 residues, is reported to be cytoplasmic and nuclear. It is a member of the Ubiquitin-conjugating enzyme family and may be known by other names, including: ubiquitin-conjugating enzyme E2N (homologous to yeast UBC13), ubiquitin carrier protein N, epididymis secretory protein Li 71, bendless-like ubiquitin conjugating enzyme, and E2 ubiquitin-conjugating enzyme N, and yeast UBC13 homolog.
