Protein function

The METTL3-METTL14 heterodimer forms a N6-methyltransferase complex that methylates adenosine residues of some RNAs and regulates the circadian clock, differentiation of embryonic stem cells and primary miRNA processing . In the heterodimer formed with METTL14, METTL3 probably constitutes the catalytic core . N6-methyladenosine (m6A), which takes place at the 5′-[AG]GAC-3′ consensus sites of some mRNAs, plays a role in the efficiency of mRNA splicing, processing, translation efficiency, editing and mRNA stability . M6A regulates the length of the circadian clock: acts as a early pace-setter in the circadian loop by putting mRNA production on a fast-track for facilitating nuclear processing, thereby providing an early point of control in setting the dynamics of the feedback loop (By similarity). M6A also acts as a regulator of mRNA stability: in embryonic stem cells (ESCs), m6A methylation of mRNAs encoding key naive pluripotency-promoting transcripts results in transcript destabilization, promoting differentiation of ESCs (By similarity). M6A also takes place in other RNA molecules, such as primary miRNA (pri-miRNAs) . METTL3 also mediates methylation of pri-miRNAs, marking them for recognition and processing by DGCR8 . Acts as a positive regulator of mRNA translation independently of the methyltransferase activity: promotes translation by interacting with the translation initiation machinery in the cytoplasm . Its overexpression in a number of cancer cells suggests that it may participate to cancer cell proliferation by promoting mRNA translation .

Protein tissue specificity

Widely expressed at low level. Expressed in spleen, thymus, prostate, testis, ovary, small intestine, colon and peripheral blood leukocytes.

Protein sequence and domain

Gate loop 1 and gate loop 2 regions are adjacent to the S-adenosyl-L-homocysteine-binding site and display large conformational changes upon ligand-binding. They may play an important role in adenosine recognition. The interface loop contributes to the heterodimer interaction.Belongs to the MT-A70-like family.

Protein cellular localization

Nucleus . Nucleus speckle . Cytoplasm . Note: Colocalizes with speckles in interphase nuclei. Suggesting that it may be associated with nuclear pre-mRNA splicing components.


This gene encodes the 70 kDa subunit of MT-A which is part of N6-adenosine-methyltransferase. This enzyme is involved in the posttranscriptional methylation of internal adenosine residues in eukaryotic mRNAs, forming N6-methyladenosine.
