Histone Acetylation in Conjugating
We have monitored histone acetylation during conjugation of the ciliated protozoan Tetrahymena thermophila using antibodies against the tetraacetylated form of H4 histone (Pfeffer, U., N. Ferrari, and G. Vidali. 1986. J. Biol. Chem. 261:2496-2498). During meiosis, the three prezygotic divisions, fertilization, and the first postzygotic division, micronuclei, do not contain highly acetylated for...
متن کاملHistone acetylation in gene regulation.
Genetic information is packaged in the highly dynamic nucleoprotein structure called chromatin. Many biological processes are regulated via post-translational modifications of key proteins. Acetylation of lysine residues at the N-terminal histone tails is one of the most studied covalent modifications influencing gene regulation in eukaryotic cells. This review focuses on the role of enzymes in...
متن کاملHistone acetylation and hormone action. Early effects of aldosterone on histone acetylation in rat kidney.
Histone acetylation in the kidney of the adrenalectomized rat was increased 5 min after a physiological dose of aldosterone. The increase was exclusively in the histone F2a1. The increase in histone acetylation was given by 9alpha-fluorocortisol, deoxycorticosterone and cortisol, but not by progesterone. The increase in histone acetylation was abolished by prior treatment of the animals with th...
متن کاملhistone acylation beyond acetylation: terra incognita in chromatin biology
histone acetylation, one of the first and best studied histone post-translational modifications (ptms), as well as the factors involved in its deposition (writers), binding (readers) and removal (erasers), have been shown to act at the heart of regulatory circuits controlling essential cellular functions. the identification of a variety of competing histone lysine-modifying acyl groups includin...
متن کاملHistone acetylation increases chromatin accessibility.
In eukaryotes, the interaction of DNA with proteins and supramolecular complexes involved in gene expression is controlled by the dynamic organization of chromatin inasmuch as it defines the DNA accessibility. Here, the nuclear distribution of microinjected fluorescein-labeled dextrans of 42 kDa to 2.5 MDa molecular mass was used to characterize the chromatin accessibility in dependence on hist...
