**Background of Recombinant Human RSAFD1 Protein**
Recombinant human RSAFD1 (Radical S-Adenosyl Methionine Domain-Containing 1) protein is a genetically engineered variant of the naturally occurring RSAFD1 protein, which belongs to the Radical SAM enzyme superfamily. This family is characterized by a conserved [4Fe-4S] cluster-binding motif (CxxxCxxC) that enables S-adenosylmethionine (SAM)-dependent catalytic activity, often involved in radical-mediated biochemical reactions. RSAFD1 is implicated in diverse cellular processes, including post-transcriptional RNA modification, iron-sulfur cluster biogenesis, and mitochondrial function. Studies suggest its potential role in regulating cellular redox homeostasis and DNA repair mechanisms, though its precise biological functions remain under investigation.
The recombinant form is typically produced in prokaryotic (e.g., *E. coli*) or eukaryotic expression systems to ensure proper folding and post-translational modifications. Its production facilitates biochemical and structural studies, such as elucidating substrate specificity, catalytic mechanisms, and interactions with nucleic acids or partner proteins. RSAFD1 has garnered interest in biomedical research due to its possible links to mitochondrial disorders, neurodegenerative diseases, and cancer progression. Recent advances in structural biology, including cryo-EM and X-ray crystallography, are aiding in decoding its molecular architecture, which may inform therapeutic targeting strategies. Further research is needed to fully unravel its physiological and pathological significance.
