RNA-Sequencing of Control KD and KD for Ime4-dMettl14, Fl(2)d, Vir, Nito, CG7358 in S2R+ cells

ABSTRACT: N6-methyladenosine (m6A) is an abundant RNA 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, Flacc controls m6A levels and is involved in sex determination in Drosophila. We demonstrate that Flacc promotes the recruitment of the methyltransferase to mRNA by bridging Fl(2)d to the mRNA binding factor Spenito. Altogether, our work advances our molecular understanding of conservation and regulation of the m6A machinery.

m6A controls neurogenesis and sex determination in Drosophila via its nuclear reader protein YT521-B [MeRIP-Seq, S2R+ cells]

Project description:N6-methyladenosine RNA (m6A) is the most abundant internal mRNA modification in mammals. While its role in the regulation of posttranscriptional gene expression is beginning to be unveiled, its function during development of complex organisms is poorly understood. Here, we identify Spenito as a novel member of the methyltransferase complex and show that m6A in Drosophila is necessary for proper synaptic growth, and in regulation of early steps of pre-mRNA splicing. Splicing of Sex-lethal and of its downstream targets are defective in animals lacking m6A, revealing also important roles in sex determination and dosage compensation. Finally, we implicate the nuclear m6A reader protein, YT521-B, as a crucial effector of m6A modifications in vivo. Altogether, our work provides important novel insights into m6A biology through identification and characterization of both m6A-writing and -reading proteins in Drosophila and their effects on splicing, neurogenesis and sex-determination within the context of the whole animal.

A novel RNA m6A modulator Zc3h13 plays an anchor role in facilitating nuclear RNA methylation and mouse embryonic stem cell self-renewal

Project description:N6-methyladenosine (m6A) is an abundant modification in eukaryotic mRNA, regulating mRNA dynamics by influencing mRNA stability, splicing, export and translation. Recent studies discovered m6A methyltransferases (?writer?), demethylases (?eraser?) and binding proteins (?reader?), which modulate m6A methylation. However, the precise m6A regulating machinery still remains incompletely understood. Here we demonstrate that ZC3H13, a zinc finger protein, plays an essential role in modulating m6A methylation on polyadenylated RNA in the nucleus. ZC3H13 exists in an evolutionary-conserved macromolecular complex containing WTAP, Virilizer and Hakai. We confirm the interaction among those proteins and demonstrate that knockdown of Zc3h13 in mouse embryonic stem cell (mESC) significantly decreases global m6A level on mRNA, mainly at 3? untranslated regions (3? UTR). Interestingly, fractionation assays show that upon Zc3h13 knockdown a great majority of WTAP, Virilizer and Hakai translocate to the cytoplasm and the nuclear presence of the methyltransferase Mettl3 and Mettl14 also decrease significantly. In contrast, knockdown of WTAP, Virilizer or Hakai does not change the nuclear localization of Zc3h13. This suggests that Zc3h13 is required for nuclear localization of the Zc3h13-WTAP-Virilizer-Hakai complex, which is important for RNA m6A methylation. Finally, Zc3h13 depletion, as does WTAP, Virilizer or Hakai, impairs self-renewal and triggers mESC differentiation. Taken together, our findings demonstrate that Zc3h13 plays an essential role in anchoring WTAP, Virilizer and Hakai in the nucleus to facilitate m6A methylation and to regulate mESC self-renewal.

Hakai is required for stabilization of core components of the m6A mRNA methylation machinery

Project description:N6-methyladenosine (m6A) is the most abundant internal modification on mRNA which influences most steps of mRNA metabolism and is involved in several biological functions. The E3 ubiquitin ligase Hakai was previously found in complex with components of the m6A methylation machinery in plants and mammalian cells but its precise function remained to be investigated. Here we show that Hakai is a conserved component of the methyltransferase complex in Drosophila and human cells. In Drosophila, its depletion results in reduced m6A levels and altered m6A-dependent functions including sex determination. We show that its ubiquitination domain is required for dimerisation and interaction with other members of the m6A machinery, while its catalytic activity is dispensable. Finally, we demonstrate that the loss of Hakai destabilizes several subunits of the methyltransferase complex, resulting in impaired m6A deposition. Our work adds new functional and molecular insights into the mechanism of the m6A mRNA writer complex.
