Highlights•DGCR8 binds to nascent mRNAs, inhibiting their transcription by sequestering FLII•Phosphorylated FLII, induced by the ERK pathway, dissociates from DGCR8 and binds to JUN•FLII facilitates JUN in activating gene expression related to cell migration•The interplay a DGCR8/FLII/JUN governs morphogenesis of implanting embryosSummaryDuring implantation, embryos undergo an unpolarized-to-polarized transition to initiate postimplantation morphogenesis.
