METTL3 (METTL3)

Methyltransferase-like 3 (METTL3) is an enzyme that functions as a key methyltransferase in the process of N6-methyladenosine (m6A) RNA methylation. METTL3 contains a catalytic domain that is responsible for the transfer of methyl groups to adenosine residues in RNA. METTL3 usually forms a complex with METTL14 and other proteins to enhance its catalytic activity and substrate specificity. The m6A modification mediated by METTL3 plays crucial roles in various biological processes, including RNA splicing, stability, translation efficiency and degradation. METTL3 is involved in the regulation of gene expression and has a significant impact on cell differentiation, development and disease occurrence. Dysregulation of METTL3 has been implicated in many human diseases, especially in the occurrence and development of various cancers^[1][2].
