CC -!- FUNCTION: S-adenosyl-L-methionine-dependent methyltransferase that
CC mediates RNA cap1 2'-O-ribose methylation to the 5'-cap structure of
CC RNAs. Methylates the ribose of the first nucleotide of a m(7)GpppG-
CC capped mRNA to produce m(7)GpppNmp (cap1).
CC {ECO:0000256|RuleBase:RU368012}.
CC -!- FUNCTION: S-adenosyl-L-methionine-dependent methyltransferase that
CC mediates mRNA cap1 2'-O-ribose methylation to the 5'-cap structure of
CC mRNAs. Methylates the ribose of the first nucleotide of a m(7)GpppG-
CC capped mRNA and small nuclear RNA (snRNA) to produce m(7)GpppRm (cap1).
CC Displays a preference for cap0 transcripts. Cap1 modification is linked
CC to higher levels of translation. May be involved in the interferon
CC response pathway. {ECO:0000256|ARBA:ARBA00002664}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 5'-end (N(7)-methyl 5'-triphosphoguanosine)-ribonucleoside
CC in mRNA + S-adenosyl-L-methionine = a 5'-end (N(7)-methyl 5'-
CC triphosphoguanosine)-(2'-O-methyl-ribonucleoside) in mRNA + H(+) + S-
CC adenosyl-L-homocysteine; Xref=Rhea:RHEA:67020, Rhea:RHEA-COMP:17167,
