METTL16 (Methyltransferase-like protein 16), also known as U6 small nuclear RNA (adenine-(43)-N(6))- methyltransferase or METT10D (Methyltransferase 10 Domain-Containing Protein), is a RNA N6-methyltransferase that methylates adenosine residues of a subset of mRNAs and U6 small nuclear RNAs (U6 snRNAs). In contrast to the METTL3-METTL14 heterodimer, METTL16 is only able to methylate a limited number of RNAs: requires both a 5UACAGAGAA-3 nonamer sequence and a specific RNA structure. It also plays a key role in S-adenosyl-L-methionine homeostasis by regulating expression of MAT2A transcripts. In presence of S-adenosyl-L-methionine, METTL16 binds the 3-UTR region of MAT2A mRNA and specifically N6-methylates the first hairpin of MAT2A mRNA, leading to intron retention and preventing MAT2A mRNA splicing. While in S-adenosyl-L-methionine-limiting conditions, it binds the 3-UTR region of MAT2A mRNA but stalls due to the lack of a methyl donor, leading to stimulate splicing of the MAT2A retained intron, and promoting expression of MAT2A.
