MT-A70 is the S-adenosylmethionine-binding subunit of human mRNA:m6A methyl-transferase (MTase), an enzyme that sequence-specifically methylates adenines in pre-mRNAs.
N6-methyladenosine (m6A) is present at internal sites in some mRNAs. m6A affects different aspects of mRNA metabolism, such as half-life, splicing, and translation [PUBMED:24284625, PUBMED:26751643, PUBMED:26593424, PUBMED:26046440, PUBMED:25799998].
