mRNA Cap 2´-O-Methyltransferase adds a methyl group at the 2´-O position of the first nucleotide adjacent to the cap structure at the 5´ end of the RNA. The enzyme utilizes S-adenosylmethionine (SAM) as a methyl donor to methylate capped RNA (cap-0) resulting in a cap-1 structure. Recently, it has been reported that the 2′-O-methylationin the cap-1 structure helps the mRNA evade innate immune response in some cell types in vivo (1,2).mRNA Cap 2´-O-Methyltransferase specifically requires RNA with an m7GpppN cap as substrate. It cannot utilize RNA with pN, ppN, pppN or GpppN at the 5´ end (3,4). Capped RNA may be prepared via in vitro transcription using cap analog or through enzymatic capping using the Vaccinia Capping Enzyme (NEB #M2080 ). The reagents provided in this pack can be used to methylate up to 400 μg of capped RNA.
