The core histone tail domains are key regulatory elements in chromatin. The tails are essential for folding oligonucleosomal arrays into both secondary and tertiary structures, and post-translational modifications within these domains can directly alter DNA accessibility. Unfortunately, there is little understanding of the structures and interactions of the core histone tail domains or how post-translational modifications within the tails may alter these interactions. Here we review NMR, thermal denaturation, cross-linking, and other selected solution methods used to define the general structures and binding behavior of the tail domains in various chromatin environments. All of these methods indicate that the tail domains bind primarily electrostatically to sites within chromatin. The data also indicate that the tails adopt specific structures when bound to DNA and that tail structures and interactions are plastic, depending on the specific chromatin environment. In addition, post-translational modifications, such as acetylation, can directly alter histone tail structures and interactions.

ABSTRACT Reconstitution of a DNA fragment containing a 5S RNA gene from Xenopus borealis into a nucleosome greatly restricts binding of the primary 5S transcription factor, TFIIIA. Consistent with transcription experiments using reconstituted templates, removal of the histone tail domains stimulates TFIIIA binding to the 5S nucleosome greater than 100-fold. However, we show that tail removal increases the probability of 5S DNA unwrapping from the core histone surface by only approximately fivefold. Moreover, using site-specific histone-to-DNA cross-linking, we show that TFIIIA binding neither induces nor requires nucleosome movement. Binding studies with COOH-terminal deletion mutants of TFIIIA and 5S nucleosomes reconstituted with native and tailless core histones indicate that the core histone tail domains play a direct role in restricting the binding of TFIIIA. Deletion of only the COOH-terminal transcription activation domain dramatically stimulates TFIIIA binding to the native nucleosome, while further C-terminal deletions or removal of the tail domains does not lead to further increases in TFIIIA binding. We conclude that the unmodified core histone tail domains directly negatively influence TFIIIA binding to the nucleosome in a manner that requires the C-terminal transcription activation domain of TFIIIA. Our data suggest an additional mechanism by which the core histone tail domains regulate the binding of trans-acting factors in chromatin.
