CDCA7 and HELLS form a stoichiometric bipartite nucleosome remodeling complex on chromatin; HELLS alone lacks remodeling activity but the CDCA7-HELLS complex possesses nucleosome remodeling activity. CDCA7 is essential for loading HELLS onto chromatin, and ICF patient mutations in CDCA7 abolish this recruitment. |

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

The CDCA7 C-terminal cysteine-rich domain (CRD) adopts a unique zinc-binding structure that recognizes a CpG dyad in a non-B DNA structure with strand-specific CpG hemi-methylation. ICF mutants fail to bind this non-B DNA. At S phase, CDCA7 concentrates in constitutive heterochromatin foci in a CRD-dependent manner. |

The central region of CDCA7 is critical for binding to HELLS and for activating HELLS ATPase and nucleosome sliding activities; the N-terminal region inhibits ATPase activity; the C-terminal 4CXXC zinc finger domain confers preference for hemimethylated CpG DNA in HELLS-CDCA7 ATPase activity. CDCA7 and HELLS show replication-dependent pericentromeric heterochromatin foci formation in mouse ES cells, lost with ICF zinc finger mutations. |

CDCA7 co-immunoprecipitates with C-NHEJ proteins Ku80 and Ku70 (interaction sensitive to nuclease treatment and abrogated by ICF3 mutation impairing chromatin binding). CDCA7- and HELLS-deficient HEK293 cells display compromised C-NHEJ activity, delayed Ku80 accumulation at DNA damage sites, increased γH2AX, aneuploidy, and centrosome amplification. CDCA7 and HELLS are also required for CG methylation maintenance at centromeric/pericentromeric repeats. |

AKT phosphorylates CDCA7 at threonine 163, promoting CDCA7 binding to 14-3-3, dissociation from MYC, and cytoplasmic sequestration. CDCA7 associates with MYC in a phosphorylation-dependent manner. Upon serum withdrawal, CDCA7 expression in the presence of MYC sensitizes cells to apoptosis; CDCA7 knockdown reduces MYC-dependent apoptosis. MYC-induced transformation of fibroblasts is reduced by CDCA7 co-expression. |

ZBTB24 directly controls Cdca7 expression: ZBTB24 is enriched at the CDCA7 promoter by ChIP and loss of Zbtb24 causes Cdca7 to be the top down-regulated gene in mESCs; CDCA7 levels are reduced in ICF2 patients carrying ZBTB24 nonsense mutations. This establishes a transcriptional hierarchy where ZBTB24 acts upstream of CDCA7. |

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

Cdca7 is a direct transcriptional target of Notch1/RBPj in the aorta-gonad-mesonephros (AGM) region; ChIP-on-chip identified the Cdca7 promoter as enriched for RBPj and Notch1. CDCA7 knockdown in AGM cells induces hematopoietic differentiation and loss of progenitor population; loss-of-function in zebrafish impairs hematopoietic stem cell emergence. |

CDCA7 is required for lymphoma cell migration and invasion; its knockdown disrupts actomyosin and tubulin cytoskeleton polarization, increases filamentous actin, and induces myosin activation. Inhibitors of actin polymerization, myosin II, or ROCK restore migration capacity of CDCA7-silenced cells, placing CDCA7 upstream of the actomyosin cytoskeleton in lymphoma cell motility. |

The ZBTB24-CDCA7-HELLS axis maintains DNA methylation at the Dux cluster in mouse ESCs, suppressing 2C-like reprogramming. Disruption of CDCA7 causes Dux hypomethylation and derepression; CDCA7 is enriched at the Dux cluster by ChIP and recruits the CDCA7-HELLS complex to constitutive heterochromatin. Site-specific re-methylation at the Dux promoter reverses the 2C-like state. |

CDCA7 acts as a transcriptional repressor and epigenetic regulator of clustered protocadherin isoform choice in the brain in vivo; a pathogenic Cdca7 missense variant leads to aberrant DNA hypomethylation in B genomic compartment domains, increased protocadherin isoform expression, gain of H3K4me3, and increased CTCF binding, without affecting H3K9me3 deposition. |
