A combinatorial H4 tail library for exploring the histone code.
Histone modifications modulate chromatin structure and function. A posttranslational modification-randomized, combinatorial library based on the first 21 residues of histone H4 was designed for systematic examination of proteins that interpret a histone code. The 800-member library represented all permutations of most known modifications within the N-terminal tail of histone H4. To determine it...
متن کاملGenomic characterization reveals a simple histone H4 acetylation code.
The histone code hypothesis holds that covalent posttranslational modifications of histone tails are interpreted by the cell to yield a rich combinatorial transcriptional output. This hypothesis has been the subject of active debate in the literature. Here, we investigated the combinatorial complexity of the acetylation code at the four lysine residues of the histone H4 tail in budding yeast. W...
متن کاملStructure and binding of the H4 histone tail and the effects of lysine 16 acetylationw
The H4 histone tail plays a critical role in chromatin folding and regulation—it mediates strong interactions with the acidic patch of proximal nucleosomes and its acetylation at lysine 16 (K16) leads to partial unfolding of chromatin. The molecular mechanism associated with the H4 tail/acidic patch interactions and its modulation via K16 acetylation remains unknown. Here we employ a combinatio...

متن کاملHistone Tail Modifications of H3 and H4 during the Physarum polycephalum Cell Cycle
Problem statement: Histone modifications are required for chromatin activities and are believed to form an epigenetic code. However, the inheritance of the histone post-translational modifications remains unclear. Approach and Results: The aim of this study was to evaluate the histone modifications throughout the cell cycle and to determine whether the histone marks are transferred to daughter ...
