ISCU Human Recombinant fused with a 21 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 154 amino acids (35-167 a.a.) and having a molecular mass of 16.7kDa. The ISCU is purified by proprietary chromatographic techniques.
Iron-sulfur cluster assembly enzyme (ISCU) belongs to the nifU family. Iron-sulfur (Fe-S) clusters are required for several mitochondrial enzymes and other subcellular compartment proteins. ISCU interacts with ISCS (a cysteine desulfurase) to sequester inorganic sulfur for Fe-S cluster assembly. The ISCU-ISCS protein complex localizes in both mitochondria and cytosol, implying that Fe-S cluster assembly occurs in multiple subcellular compartments in mammalian cells.
