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] [SWR1_YEAST] Catalytic component of the SWR1 complex which mediates the ATP-dependent exchange of histone H2A for the H2A variant HZT1 leading to transcriptional regulation of selected genes by chromatin remodeling.[10] [11] [12] [13]

About this Structure

4m6b is a 4 chain structure. Full crystallographic information is available from OCA.
