Influence of histone tails and H4 tail acetylations on nucleosome-nucleosome interactions.

Abstract excerpt

Nucleosome-nucleosome interaction plays a fundamental role in chromatin folding and self-association. The cation-induced condensation of nucleosome core particles (NCPs) displays properties similar to those of chromatin fibers, with important contributions from the N-terminal histone tails. We study the self-association induced by addition of cations [Mg(2+), Ca(2+), cobalt(III)hexammine(3+), spermidine(3+) and...
