Abstract

© 2017 The Author(s). Published with license by Taylor & Francis © 2017, © Madapura M. Pradeepa. Enhancers control development and cellular function by spatiotemporal regulation of gene expression. Co-occurrence of acetylation of histone H3 at lysine 27 (H3K27ac) and mono methylation of histone H3 at lysine 4 (H3K4me1) has been widely used for identification of active enhancers. However, increasing evidence suggests that using this combination of marks alone for enhancer identification gives an incomplete picture of the active enhancer repertoire. We have shown that the H3 globular domain acetylations, H3K64ac and H3K122ac, and an H4 tail acetylation, H4K16ac, are enriched at active enhancers together with H3K27ac, and also at a large number of enhancers without detectable H3K27ac. We propose that acetylations at these lysine residues of histones H3 and H4 might function by directly affecting chromatin structure, nucleosome–nucleosome interactions, nucleosome stability, and transcription factor accessibility.
