CRL4-DCAF13 acts as an E3 ubiquitin ligase complex that targets SUV39H1 for polyubiquitination and proteasomal degradation, thereby facilitating H3K9me3 removal and enabling zygotic gene expression during preimplantation embryonic development. Dcaf13 knockout mice arrest at the 8-16 cell stage with elevated H3K9me3. |

DCAF13 is a nucleolar protein that functions as a component of the rRNA-processing complex essential for 18S rRNA processing in growing oocytes. DCAF13 interacts with the box C/D ribonucleoprotein component fibrillarin. Conditional knockout of Dcaf13 causes pre-rRNA accumulation, ribosome assembly disorder, reduced global protein synthesis, and arrest of oocyte NSN-to-SN chromatin configuration transition. |

Maternal DCAF13, highly expressed in the growing oocyte nucleolus, is required for chromatin tightness in fully grown germinal vesicle oocytes and for proper chromosome condensation at MII. Loss of maternal DCAF13 leads to loose chromatin structure in GV oocytes, improperly condensed MII chromosomes, abnormal nuclear/nucleolar reorganization, and inactive transcription in zygotes, causing two-cell stage arrest. |

DCAF13 functions as an RNA-binding protein (RBP) that binds to the AU-rich element (ARE) in the 3'UTR of DTX3 mRNA to accelerate its degradation, thereby activating NOTCH4 signaling (since DTX3 normally promotes ubiquitination and degradation of NOTCH4) and promoting triple-negative breast cancer metastasis. |

CRL4-DCAF13 E3 ligase targets PERP for ubiquitination and proteasomal degradation in breast cancer cells. Co-immunoprecipitation showed DCAF13 and DDB1 directly interact with PERP, and DDB1 overexpression significantly increased PERP polyubiquitination. DCAF13 deletion causes both mRNA and protein accumulation of PERP, leading to apoptosis and senescence. |

DCAF13 is identified as the substrate receptor (DDB1- and Cullin-associated factor) of the CRL4 ubiquitin ligase that recognizes TOP1-DNA-protein crosslinks (TOP1-DPCs) for ubiquitination and proteasomal degradation during replication-coupled repair. The CUL4-RBX1 complex undergoes auto-NEDD8 modification and acts on TOP1-DPCs. |

DCAF13 promotes NPM1 phase separation in nucleolar condensates to accelerate pre-rRNA enrichment and recruitment of the endonuclease UTP23, thereby facilitating 18S rRNA maturation and rapid T cell proliferation. DCAF13 depletion in T cells causes 18S rRNA maturation failure, abnormal ribosome assembly in nucleoli, and insufficient nascent protein production. |

CRL4-DCAF13 E3 ubiquitin ligase targets MeCP2 (methyl-CpG-binding protein 2) for polyubiquitination and proteasomal degradation in growing oocytes. Dcaf13-null oocytes accumulate MeCP2 protein, leading to transcription dysregulation and DNA hypermethylation; partial rescue of follicle growth arrest was achieved by MeCP2 knockdown. |
