[[http://www.uniprot.org/uniprot/H2B11_XENLA H2B11_XENLA]] Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling.

== Publication Abstract from PubMed ==
The conformation of DNA bound in nucleosomes depends on the DNA sequence. Questions such as how nucleosomes are positioned and how they potentially bind sequence-dependent nuclear factors require near-atomic resolution structures of the nucleosome core containing different DNA sequences; despite this, only the DNA for two similar alpha-satellite sequences and a sequence (601) selected in vitro have been visualized bound in the nucleosome core. Here we report the 2.6-A resolution X-ray structure of a nucleosome core particle containing the DNA sequence of nucleosome A of the 3'-LTR of the mouse mammary tumor virus (147 bp MMTV-A). To our knowledge, this is the first nucleosome core particle structure containing a promoter sequence and crystallized from Mg2+ ions. It reveals sequence-dependent DNA conformations not seen previously, including kinking into the DNA major groove.
