MTHFSD (Methylenetetrahydrofolate Synthase Domain-containing) recombinant protein is derived from the MTHFSD gene, which encodes an enzyme involved in folate metabolism. Folate pathways play critical roles in one-carbon transfer reactions essential for nucleotide synthesis, methylation processes, and cellular redox balance. The MTHFSD protein specifically catalyzes the conversion of 5.10-methenyltetrahydrofolate to 5-formyltetrahydrofolate (5-FTHF), a reaction vital for maintaining folate pool equilibrium and regulating one-carbon flux. Dysregulation of this enzyme has been implicated in metabolic disorders, neural tube defects, and certain cancers, highlighting its biological significance.
Recombinant MTHFSD protein is typically produced using heterologous expression systems like *E. coli* or mammalian cell cultures. These systems enable large-scale production of the purified, functional protein for structural and functional studies. The recombinant form retains enzymatic activity, allowing researchers to study its kinetics, substrate specificity, and interactions with inhibitors or modulators. Its stability and solubility are often optimized through codon engineering or fusion tags (e.g., GST or His-tags) to facilitate purification and downstream applications.
In research, MTHFSD recombinant protein is utilized to investigate folate metabolism dynamics, screen potential therapeutic compounds targeting folate-related diseases, and elucidate molecular mechanisms underlying pathologies linked to folate imbalance. Additionally, it serves as a critical tool in structural biology for X-ray crystallography or cryo-EM studies to resolve its 3D architecture, aiding in drug design. The development of MTHFSD recombinant protein underscores its importance as both a biochemical reagent and a target for translational research in metabolic and oncological fields.
