There are a number of ELISA Kits available for the measurement of ubiquitin-conjugating enzyme E2D 2, another term for the human protein, ubiquitin conjugating enzyme E2 D2. Other synonyms may include: E2 ubiquitin-conjugating enzyme D2, p53-regulated ubiquitin-conjugating enzyme 1, ubiquitin carrier protein D2, ubiquitin-conjugating enzyme E2-17 kDa 2, and ubiquitin-conjugating enzyme E2D 2 (homologous to yeast UBC4/5). It is encoded by the UBE2D2 gene to yield a protein 147 amino acids in length and 16.7 kDa in size. However, there are up to 2 reported isoforms. The protein, an enzyme, is categorized into the Ubiquitin-conjugating enzyme family. Versions of ubiquitin-conjugating enzyme E2D 2 are present in other organisms, including: Mouse, Rat, Zebrafish, Chicken.
