| + | [https://www.uniprot.org/uniprot/H32_XENLA H32_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. | ||

| + | Recognition of histone-modified nucleosomes by specific reader domains underlies the regulation of chromatin-associated processes. Whereas structural studies revealed how reader domains bind modified histone peptides, it is unclear how reader domains interact with modified nucleosomes. Here, we report the cryo-electron microscopy structure of the PWWP reader domain of human transcriptional coactivator LEDGF in complex with an H3K36-methylated nucleosome at 3.2-A resolution. The structure reveals multivalent binding of the reader domain to the methylated histone tail and to both gyres of nucleosomal DNA, explaining the known cooperative interactions. The observed cross-gyre binding may contribute to nucleosome integrity during transcription. The structure also explains how human PWWP domain-containing proteins are recruited to H3K36-methylated regions of the genome for transcription, histone acetylation and methylation, and for DNA methylation and repair. | ||
