H4K5ac (original) (raw)

H4K5ac is an epigenetic modification to the DNA packaging protein histone H4. It is a mark that indicates the acetylation at the 5th lysine residue of the histone H4 protein. H4K5 is the closest lysine residue to the N-terminal tail of histone H4. It is enriched at the transcription start site (TSS) and along gene bodies. Acetylation of histone H4K5 and H4K12ac is enriched at centromeres.
