The tandem PHD fingers of CHD5 specifically recognize the unmodified N-terminus of histone H3; modifications at H3R2, H3K4, H3T3, H3T6, and H3S10 disrupt binding, and the tandem PHD1-2 simultaneously engages two H3 N-termini with 4-11-fold increased affinity compared to individual PHD fingers. |

Chd5 binds the unmodified N-terminus of histone H3 through its tandem PHD domains; PHD mutations that abrogate H3 binding abolish Chd5's ability to inhibit proliferation, transcriptionally modulate target genes, and suppress tumor growth in vivo, establishing that chromatin binding is required for tumor suppression. |

CHD5 is a component of the full NuRD transcriptional repressor complex (containing methyl-CpG binding proteins and HDACs); overexpression of CHD5 results in loss of CHD4 protein, suggesting the CHD5/NuRD and CHD4/NuRD complexes are mutually exclusive. CHD5 binds and represses the G2/M checkpoint gene WEE1, and a catalytically inactive CHD5 mutant associates with NuRD but fails to repress transcription. |

CHD5 is a chromatin remodeling ATPase that exposes nucleosomal DNA at discrete positions (nucleosome unwrapping) in an ATP hydrolysis-dependent manner; continued ATP hydrolysis is not required to maintain the remodeled state, and this activity is distinct from ACF and BRG1, which reposition nucleosomes. CHD4 shows strong ATPase activity but does not unwrap nucleosomes as efficiently as CHD5. |

Chd5 orchestrates a cascade of molecular events during spermiogenesis required for histone removal and replacement: H4 hyperacetylation, histone variant expression, nucleosome eviction, DNA damage repair, and expression of transition proteins (Tnp1/Tnp2) and protamines (Prm1/2). Chd5 deficiency leads to defective sperm chromatin compaction and male infertility. |

CHD5 is clearly associated with all canonical NuRD components—MTA1/2, GATAD2A, HDAC1/2, RBBP4/7, and MBD2/3—as determined by immunoprecipitation from neuroblastoma cell nuclear extracts and confirmed by MS/MS analysis. GST-FOG1 pulldown also identified NuRD components associated with CHD5. |

CHD5 expression in spermatogenesis is restricted to post-meiotic round spermatids with a maximum at stage VIII, shows complementary expression with CHD3/4, and CHD5 co-localizes with macroH2A1.2 at centromeres and part of the Y chromosome in post-meiotic cells, suggesting a role in sex chromosome chromatin regulation. CHD5 was demonstrated to be a nucleosome-stimulated ATPase in vitro. |

CHD5 and EZH2 mutually repress each other's transcription: CHD5 is epigenetically silenced by PRC2-mediated H3K27me3 in HCC cells, and overexpression of CHD5 in turn represses EZH2 and activates PRC2 target genes p16 and p21. ChIP and luciferase reporter assays confirmed reciprocal promoter binding. |
