Anti-NifU antibodies enable researchers to detect and measure the NifU antigen in biological samples. This target is a reported synonym of the ISCU gene, which encodes iron-sulfur cluster assembly enzyme. This protein is known to function in electron transport, among other biological roles. The human version of NifU has a canonical amino acid length of 167 residues and a protein mass of 18 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus, mitochondria, and cytoplasm of cells and widely expressed in many tissue types. NifU is a member of the NifU protein family.
