Listed are ELISA Kits for the detection of m-Nfsl, an alias name of NFS1 cysteine desulfurase. The human protein, encoded by the gene NFS1, is 457 amino acid residues long and has a mass of 50,196 daltons. However, there are up to 3 reported isoforms. It is a member of the Class-V pyridoxal-phosphate-dependent aminotransferase family, NifS/IscS subfamily. This protein is reported to have a cytoplasmic, nuclear and mitochondrial cellular localization. This target may also be known as: cysteine desulfurase mitochondrial, NFS1 nitrogen fixation 1 homolog, nitrogen fixation 1 (S. cerevisiae homolog), nitrogen-fixing bacteria S-like protein, IscS, and NIFS.
