Anti-acetyl-Histone H4 (Lys91) Antibody

Histones are nuclear proteins that form octameric structures which bind DNA to form units of chromatin called nucleosomes. The family of histones—H2A, H2B, H3, and H4—are key players in gene regulation. They undergo a number of post-translational modifications (PTM) in response to various stimuli. Acetylation is a reversible PTM that involves the transfer of acetyl groups to N-terminal lysine (K) residues by the family of histone acetyltransferase enzymes, including GNAT, Gcn5, and p300/CBP. Histone acetylation reduces the electrostatic attractions between DNA and histones, which typically destabilizes chromatin structure and provide chromatin remodeling and transcriptional complexes with access to DNA, potentially resulting in increased gene transcription. Recent studies have suggested that acetylation of histone H4 lysine 91 facilitates the interaction of H3/H4 tetramers with H2A/H2B dimers, which is required for chromatin assembly.
