CDCA7 and HELLS form a stoichiometric bipartite nucleosome remodeling complex on chromatin; CDCA7 is essential for loading HELLS onto chromatin, and the HELLS-CDCA7 complex together possesses nucleosome remodeling activity that neither protein has alone. ICF-mutant CDCA7 fails to recruit the complex to chromatin. |

The C-terminal zinc-finger domain (HMZF/zf-4CXXC_R1) of CDCA7 is an evolutionarily conserved hemimethylated CpG sensor. Cryo-EM structural analysis of the CDCA7-nucleosome complex reveals this domain recognizes hemimethylated CpG in the outward-facing DNA major groove within the nucleosome core particle. CDCA7 recruits HELLS to hemimethylated chromatin and facilitates UHRF1-mediated H3 ubiquitylation associated with replication-uncoupled maintenance DNA methylation. ICF disease mutations abolish hemimethylated DNA binding. |

The CDCA7 C-terminal cysteine-rich domain (CRD) adopts a unique zinc-binding structure that recognizes a CpG dyad in a non-B DNA formed by two sequence motifs, with strand-specific preference for hemimethylated CpG. ICF mutant CDCA7 loses this binding. During S phase, CDCA7 concentrates in constitutive heterochromatin foci in a CRD-dependent manner, and this localization can be outcompeted by exogenous hemi-methylated non-B DNA. |

The central region of CDCA7 is critical for binding HELLS, activating HELLS ATPase activity, and enabling nucleosome sliding by the HELLS-CDCA7 complex. The N-terminal region tends to inhibit ATPase activity. The C-terminal 4CXXC-type zinc finger domain confers preference for hemimethylated CpG DNA in HELLS-CDCA7 ATPase activity, and replication-dependent pericentromeric heterochromatin foci formation of CDCA7 with HELLS requires an intact zinc finger domain. |

CDCA7 co-immunoprecipitates with C-NHEJ proteins Ku80 and Ku70 as well as HELLS; this interaction is sensitive to nuclease treatment and to an ICF3 mutation in CDCA7 that impairs chromatin binding. Loss of CDCA7 or HELLS compromises classical NHEJ activity and delays Ku80 accumulation at DNA damage sites. |

AKT phosphorylates CDCA7 at threonine 163, promoting its binding to 14-3-3 proteins, dissociation from MYC, and cytoplasmic sequestration. Dephosphorylated CDCA7 associates with MYC in the nucleus and sensitizes cells to apoptosis upon serum withdrawal; CDCA7 knockdown reduces MYC-dependent apoptosis, and CDCA7 co-expression reduces MYC-mediated transformation of fibroblasts. |

ZBTB24 directly controls transcription of CDCA7: ZBTB24 is enriched at the CDCA7 promoter by ChIP, loss of functional Zbtb24 in mouse ESCs downregulates Cdca7 as the top affected gene, and ectopic ZBTB24 expression restores Cdca7 levels. CDCA7 protein levels are reduced in patients with ZBTB24 nonsense mutations. |

CDCA7 is a direct Notch transcriptional target in the aorta-gonad-mesonephros (AGM): RBPj and Notch1 are recruited to the Cdca7 promoter by ChIP. CDCA7 expression is restricted to hematopoietic clusters in the aorta and is required for hematopoietic stem cell emergence; its knockdown in zebrafish reduces HSC formation, and its downregulation in AGM cells promotes hematopoietic differentiation and loss of progenitors. |

The CDCA7/HELLS complex is required for the accumulation of proteins on nascent DNA, including the DNMT1/UHRF1 maintenance methylation complex and R-loop resolution factors. Loss of CDCA7/HELLS leads to increased transcription and aberrant DNA:RNA hybrid (R-loop) formation at pericentromeric repeats, and ectopic RNASEH1 expression reduces DNA damage accumulation at these loci in ICF mutant cells. |

CDCA7 loss in vivo causes large aberrantly hypomethylated domains overlapping the B genomic compartment without affecting H3K9me3 deposition. In brain tissue, CDCA7 acts as a transcriptional repressor of clustered protocadherin isoforms via DNA methylation; hypomethylation at protocadherin loci upon CDCA7 loss is accompanied by gain of H3K4me3 and increased CTCF binding. |

CDCA7 and HELLS constitute a ZBTB24-CDCA7-HELLS axis that suppresses totipotent 2C-like reprogramming in mESCs by maintaining DNA methylation of the Dux cluster. CDCA7 is enriched at the Dux cluster chromatin and recruits HELLS there; disruption leads to Dux hypomethylation, derepression, and upregulation of 2C-specific genes, reversible by site-specific re-methylation at the Dux promoter. |

CDCA7 exhibits two distinct DNA-binding modes and subcellular localization patterns: diffuse nuclear distribution in interphase (binding CG-rich promoter regions) and pericentromeric heterochromatin localization in late S phase (hemimethylated DNA-dependent). An ICF-causing G294V mutation abolishes both CG-rich DNA binding and heterochromatin localization. CDCA7 recruits LSH/HELLS to both CG-rich promoters in interphase and heterochromatin domains in late S phase, and both proteins can regulate transcription independently of DNA methylation. |
