Abstract

N6-methyladenosine (m6A) is the most abundant mRNA modification in eukaryotes, playing crucial roles in multiple biological processes. m6A is catalyzed by the activity of Mettl3, which depends on additional proteins whose precise functions remain poorly understood. Here we identified Flacc/Zc3h13 as a novel interactor of m6A methyltransferase complex components in Drosophila and mouse. Like other components of this complex, Flacc controls m6A levels and is involved in sex
determination in Drosophila. We demonstrate that Flacc promotes m6A deposition by bridging Fl(2)d to the mRNA binding factor Nito. Altogether, our work advances our molecular understanding of conservation and regulation of the m6A machinery.
