This product is the mRNA Cap-2′-O-Methyltransferase of vaccinia virus recombinantly expressed in E. coli. With the RNA of 7-methylguanosine cap (Cap0) as the substrate, it specifically transfers the methyl of methylation donator SAM to the Cap0 structure in RNA to form the Cap1 structure, which can enhance the translation efficiency of mRNA and avoid the innate immune response in certain cells.
