NSUN3 (NOP2/Sun RNA Methyltransferase Family Member 3), is a member of NSUN family. Gene Ontology (GO) annotations related to this gene include RNA binding and methyltransferase activity. NSUN3 is said to be a mitochondrial tRNA methyltransferase that mediates methylation of cytosine to 5-methylcytosine (m5C) at position 34 of mt-tRNA(Met). mt-tRNA(Met) methylation at cytosine(34) takes place at the wobble position of the anticodon and initiates the formation of 5-formylcytosine (f(5)c) at this position. mt-tRNA(Met) containing the f(5)c modification at the wobble position enables recognition of the AUA codon in addition to the AUG codon, expanding codon recognition in mitochondrial translation.

Application Notes

Recombinant NSUN3 protein is suitable for use in enzyme kinetics, inhibitor screening, and selectivity profiling.
