Term Name:	mRNA 5'-cap (guanine-N7-)-methyltransferase activity
Synonyms:	guanine-7-methyltransferase activity, messenger ribonucleate guanine 7-methyltransferase activity, messenger RNA guanine 7-methyltransferase activity, S-adenosyl-L-methionine:mRNA (guanine-7-N-)-methyltransferase activity, S-adenosyl-L-methionine:mRNA (guanine-N7-)-methyltransferase activity
Definition:	Catalysis of the reaction: S-adenosyl-L-methionine + G(5')pppR-RNA = S-adenosyl-L-homocysteine + m7G(5')pppR-RNA. m7G(5')pppR-RNA is mRNA containing an N7-methylguanine cap; R may be guanosine or adenosine.
