Anti-NFS1 Antibody Picoband®

Cysteine desulfurase, mitochondrial is an enzyme that in humans is encoded by the NFS1 gene. Iron-sulfur clusters are required for the function of many cellular enzymes. The proteins encoded by this gene supply inorganic sulfur to these clusters by removing the sulfur from cysteine, creating alanine in the process. This gene uses alternate in-frame translation initiation sites to generate mitochondrial forms and cytoplasmic/nuclear forms. Selection of the alternative initiation sites is determined by the cytosolic pH. The encoded proteins belong to the class-V family of pyridoxal phosphate-dependent aminotransferases. Alternatively spliced transcript variants have been described.

E.coli-derived human NFS1 recombinant protein (Position: R107-L356) . Human NFS1 shares 96.4% and 96% amino acid (aa) sequence identity with mouse and rat NFS1, respectively.
