Anti-E2-CDC34B antibodies enable researchers to detect and measure the E2-CDC34B antigen in biological samples. This target is a reported synonym of the UBE2R2 gene, which encodes ubiquitin conjugating enzyme E2 R2. This protein is known to function in protein ubiquitination, among other biological roles. The human version of E2-CDC34B has a canonical amino acid length of 238 residues and a protein mass of 27.2 kilodaltons. Other names for this target antigen include CDC34B, CDC34B, and E2-CDC34B.
