Cap-specific mRNA (nucleoside-2'-O-)-methyltransferase 1

UniProtKB accession:  Q8N1G2

Grouped By:  Matching UniProtKB accession

UniProtKB description:  S-adenosyl-L-methionine-dependent methyltransferase that mediates mRNA cap1 2'-O-ribose methylation to the 5'-cap structure of mRNAs. 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 linked to higher levels of translation. May be involved in the interferon response pathway.
