From: m6A modification: recent advances, anticancer targeted drug discovery and beyond
The underlying mechanisms of m6A modification. The m6A modification of mRNA is mainly catalyzed by the core methylase complex METTL3-WTAP-METTL14. RBM15/15B, VIRMA/KIAA1429, and ZC3H13 are newly identified mRNA m6A writers; METTL4, and METTL16 are snRNA m6A writhers; and METTL5 and ZCCHC4 are rRNA m6A writers. The m6A modification is removed by FTO, ALKBH5, and ALKBH3. Readers recognize m6A and affect various functions of RNAs, and they mainly include members of the YTH domain-containing family, the IGF2BP family, the HNRNP family, eIF3, PRRC2A, and FMRP
