  Function in Host
S-adenosyl-L-methionine-dependent methyltransferase thatmediates mRNA cap1 2'-O-ribose methylation to the 5'-cap structure ofmRNAs. Methylates the ribose of the first nucleotide of a m (7) GpppG-capped mRNA and small nuclear RNA (snRNA) to produce m (7) GpppRm (cap1). Displays a preference for cap0 transcripts. Cap1 modification is linkedto higher levels of translation. May be involved in the interferonresponse pathway. [1-3]
