| Crosstalk Summary | Among validating hits are genes coding for the N6-methyladenosine (m6A) mRNA methyltransferase (MTase) complex, including, METTL14, METTL3, and WTAP. We demonstrate that m6A MTase activity promotes erythroid gene expression programs through selective translation of ~300 m6A marked mRNAs, including those coding for Histone-lysine N-methyltransferase SETD1A (SETD1A), SETD1B and KTM2D. Remarkably, loss of m6A marks results in dramatic loss of Histone H3 lysine 4 trimethylation (H3K4me3) marks across key erythroid-specific KLF1 transcriptional targets | ||||
