The Landscape and Regulation of Histone Crotonylation in Mammalian Gametes and Early Embryos
Advanced Science, EarlyView.Histone crotonylation undergoes a genome‐wide transition from broad domains to canonical narrow peaks during minor zygotic genome activation (ZGA). This remodeling is required for proper major ZGA and blastocyst formation. Disruption of this transition by transcriptional inhibition, metabolic perturbation, or HDAC1 dysfunction impairs embryonic ...
