In enzymology, a mRNA (guanine-N7-)-methyltransferase also known as mRNA cap guanine-N7 methyltransferase is an enzyme that catalyzes the chemical reaction

S-adenosyl-L-methionine + G(5')pppR-RNA

\rightleftharpoons

S-adenosyl-L-homocysteine + m₇G(5')pppR-RNA (mRNA containing an N⁷-methylguanine cap)

Thus, the two substrates of this enzyme are S-adenosyl methionine and G(5')pppR-RNA, whereas its two products are S-adenosylhomocysteine and m7G(5')pppR-RNA. This enzyme belongs to the family of transferases, specifically those transferring one-carbon group methyltransferases.

In humans, mRNA cap guanine-N7 methyltransferase is encoded by the RNMT gene.
