2.9 Angstrom X-ray structure of hybrid macroH2A nucleosomes2.9 Angstrom X-ray structure of hybrid macroH2A nucleosomes

Structural highlights

2f8n is a 10 chain structure with sequence from Homo sapiens, Mus musculus and Xenopus laevis. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.9Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

H2B3A_MOUSE 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.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
