These UBOX2 ELISA kits are immunodetection tools for measuring the levels of UBOX2 in biological samples. UBOX2 is an alias of the human UBE4A gene, which encodes the protein, ubiquitination factor E4A. Notably, UBOX2 is known to play a role in protein ubiquitination, among other functions. The UBE4A protein is 1066 amino acid residues in length and 122.6 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cytoplasm of the cell. Other names for this target antigen include E4 and NEDHMS. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
