FXN protein is a key activator in the core iron-sulfur cluster (ISC) assembly complex, accelerating persulfide transfer to ISCU and [2Fe-2S] cluster assembly. It promotes sulfur transfer, leading to oversulfidation and sulfide release. FXN Protein, Mouse (His) is the recombinant mouse-derived FXN protein, expressed by E. coli , with N-6*His labeled tag.
