2.3.1.48 acetyl-CoA + histone H4 Drosophila melanogaster acetylation at Lys16 by MYST1 is essential for chromatin remodeling and is used for regulation of gene expression in eukaryotes. The nucleosome is a disc-shaped octamer consisting of two heterotetramers formed by histones H3/H4 and histones H2A and H2B CoA + acetylhistone H4

2.3.1.48 acetyl-CoA + histone H4 Homo sapiens MYST1 specificity to Lys16 of histone H4 is not absolute, because in experiments in vitro the protein is also able to acetylate histones H3 and H2A, whereas in vivo only modification of histone H4 is specific. Acetylation at Lys16 by MYST1 is essential for chromatin remodeling and is used for regulation of gene expression in eukaryotes. The nucleosome is a disc-shaped octamer consisting of two heterotetramers formed by histones H3/H4 and histones H2A and H2B. All human autosomes are susceptible to histone H4 acetylation by Lys16 residue and acetyltransferase MYST1 CoA + acetylhistone H4

2.3.1.48 additional information Drosophila melanogaster MYST1 is a part of multiprotein complexes that accomplish functions of male X chromosome activation and thereby functions of dosage compensation in Drosophila and, in mammals, global acetylation of histone H4 K16. Functional links between MYST1 and proteins ATM and p53. Interactions between MSL1 and MYST1 within the MSL complex in Drosophila melanogaster, the compensasome includes proteins MSL1, MSL2, MSL3, MLE, MOF, a histone acetyltransferase homologous to MYST1, JIL1, and two non-coding RNA: roX1 and roX2, structure and function of the compensasome, detailed overview.
