Permissive chromatin marks
WebFurther experiments revealed that DNMT3L specifically interacts with the seven N-terminal amino acids of histone H3. Crucially, this interaction is abolished upon histone H3 lysine 4 methylation (H3K4me1,2,3—permissive chromatin mark), but was insensitive to H3K27 or H3K9 methylation (repressive chromatin marks) .

WebJan 23, 2012 · Apart from physiological changes in the exposed generation, stress also alters epigenetic marks that can potentially persist in the progeny. Epigenetic factors can contribute to both short-term (mitotic) and long-term (meiotic) inheritance of an altered gene expression without changing the primary DNA sequences [1].
