Function

[H2B1_YEAST] 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.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7] ^[8] ^[9] [CHZ1_YEAST] Forms a chaperone-bound H2A.Z-H2B complex that acts as a source for SWR1 complex-dependent H2A to H2A.Z histone replacement in chromatin.^[10]

Publication Abstract from PubMed

The NMR structure of budding yeast chaperone Chz1 complexed with histones H2A.Z-H2B has been determined. Chz1 forms a long irregular chain capped by two short alpha-helices, and uses both positively and negatively charged residues to stabilize the histone dimer. A molecular model that docks Chz1 onto the nucleosome has implications for its potential functions.
