Anti-NSE4B antibodies enable researchers to detect and measure the NSE4B antigen in biological samples. This target is a reported synonym of the EID3 gene, which encodes EP300 interacting inhibitor of differentiation 3. This protein is known to function in DNA repair, among other biological roles. The human version of NSE4B has a canonical amino acid length of 333 residues and a protein mass of 38.2 kilodaltons. It is reported to be localized in the nucleus and cytoplasm of cells. NSE4B is a member of the NSE4 protein family.
