Protein attributes

Sequence length	685 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Probable N6-methyltransferase that methylates adenosine residues of some mRNAs. N6-methyladenosine (m6A), which is present at internal sites of some mRNAs, may play a role in the efficiency of mRNA splicing, transport or translation By similarity.
Catalytic activity	S-adenosyl-L-methionine + m7G(5')pppAm = S-adenosyl-L-homocysteine + m7G(5')pppm6Am.
Subcellular location	Nucleus Probable.
Sequence similarities	Belongs to the MT-A70-like family.
Sequence caution	The sequence AAC35526.1 differs from that shown. Reason: Erroneous gene model prediction. The sequence AK227385 differs from that shown. Reason: Frameshift at position 206.
