WDR68 (DCAF7) interacts with DYRK1A and DYRK1B kinases and is required for craniofacial development in zebrafish; a GFP-WDR68 fusion protein localizes to the nucleus with DYRK1A, whereas a loss-of-function mutant (Wdr68-T284F) fails to accumulate in the nucleus and fails to rescue wdr68 mutant animals, placing WDR68 upstream of the edn1 pathway. |

HAN11 (DCAF7) acts as a scaffold protein that directly binds HIPK2, DYRK1A, DYRK1B, and MEKK1 in vitro, and is required to couple MEKK1 to DYRK1/HIPK2; knockdown lowers the threshold and amplitude of HIPK2- and MEKK1-triggered signaling, while overexpression impairs stoichiometrically assembled signaling complexes. |

C. elegans SWAN-1 (DCAF7 ortholog) physically interacts with EGL-9 (prolyl hydroxylase) by yeast two-hybrid and co-immunoprecipitation; genetic evidence places the DYRK kinase MBK-1 downstream of SWAN-1 to promote HIF-1-mediated transcription and resistance to P. aeruginosa. |

SWAN-1 (DCAF7 ortholog in C. elegans) physically associates with Rac GTPases and the LIM domains of the Rac effector UNC-115/abLIM; swan-1 loss-of-function suppresses ced-10 (Rac) hypomorphic defects and enhances constitutively active Rac phenotypes, identifying SWAN-1 as a negative regulator of Rac GTPase function in cytoskeletal organization. |

WDR68 (DCAF7) binds DYRK1A and DYRK1B (but not DYRK2, 3, or 4) via DYRK1A's N-terminal domain (not the kinase domain); co-expression of wild-type or kinase-dead DYRK1A drives nuclear accumulation of WDR68, indicating that binding (not phosphorylation) mediates nuclear translocation; WDR68 depletion induces cell apoptosis. |

Nuclear access is required for WDR68 function in craniofacial development: a nuclear-export-signal (NES) fusion of WDR68 fails to rescue craniofacial defects and redistributes DYRK1A to the cytoplasm; a transcriptional activation domain fusion rescues development whereas a transcriptional repression domain fusion does not; WDR68 promotes myogenin promoter activity in C2C12 cells. |

The molecular chaperone TRiC/CCT binds WDR68 via three of its seven β-propeller blades; TRiC/CCT knockdown causes abnormal WDR68 folding, reduces DYRK1A-binding activity, suppresses nuclear accumulation of WDR68, and causes WDR68 aggregation upon overexpression. Phosphorylation sites in both WDR68 and TRiC/CCT were identified. |

DCAF7 (WDR68/HAN11) acts as an adaptor that bridges adenovirus E1A to DYRK1A and HIPK2; a 12-amino-acid DCAF7-binding motif in the N-terminal domain of class 1 DYRKs is functionally conserved across species; a similar sequence mediates DCAF7 binding to HIPK2, whereas HIPK1 does not bind DCAF7; DCAF7 is required for hyperphosphorylation of E1A by DYRK1A or HIPK2, defining it as a substrate-recruiting subunit. |

DCAF7 is the specificity/substrate-recognition factor for the Cul4-DDB1 E3 ubiquitin ligase complex that targets DNA ligase I for ubiquitylation and degradation; three ubiquitylated lysine residues on DNA ligase I were mapped, and mutation of these residues reduced in vitro ubiquitylation by Cul4-DDB1-DCAF7; DCAF7 knockdown reduced DNA ligase I degradation upon inhibition of proliferation. |

DCAF7 (Dcaf7/WDR68) is a component of neuronal stigmoid bodies that interacts with Huntingtin-associated protein 1 (Hap1); Hap1 competes with DYRK1A for cytoplasmic binding to Dcaf7, thereby regulating Dcaf7 nuclear translocation; depleting Hap1 promotes DYRK1A-Dcaf7 interaction, increases DYRK1A protein levels, and overexpression of DYRK1A in hypothalamus causes delayed postnatal growth in mice. |

WDR68 (DCAF7) is required for normal protein levels of DYRK1A and DYRK1B: deletion of Wdr68 reduces DYRK1A/1B protein without affecting Dyrk1a mRNA levels or proteasome-dependent degradation; overexpression of WDR68 increases DYRK1A protein; DYRK1A and DYRK1B are each required for the transition from proliferation to differentiation in C2C12 cells. |

WDR68 (DCAF7) is an integral component of the PRC1-AUTS2 complex and is required for PRC1-AUTS2-mediated transcriptional activation; deletion of Wdr68 in mouse embryonic stem cells causes defects in neuronal differentiation without affecting self-renewal, with down-regulation of PRC1-AUTS2 target neuronal genes. |

DYRK1A exists in a complex with DCAF7 that stabilizes DYRK1A and tethers it to RNA Pol II; this DYRK1A-DCAF7 complex phosphorylates the CTD of Pol II and co-migrates with Pol II along myogenic gene loci to stimulate myogenic transcription after P-TEFb is eliminated during myoblast differentiation. |

DCAF7 interacts with the ERCC1-XPF endonuclease complex (primarily with XPF); DCAF7 knockdown reduces cellular ERCC1-XPF protein levels partly via proteasomal degradation and impairs nucleotide excision repair of UV-induced (6-4) photoproducts; depletion of TRiC/CCT also reduces ERCC1-XPF levels, linking chaperone-assisted DCAF7 folding to NER capacity. |

DCAF7 proximally interacts with IRS1 (insulin/IGF1 signaling adaptor) as well as DYRK1A and DYRK1B; DCAF7 knockdown in HepG2 cells attenuates insulin-stimulated AKT phosphorylation, promotes nuclear localization of FOXO1, induces FOXO1 target genes involved in G2 cell cycle inhibition, and causes G2 arrest; in Drosophila, wing-specific knockdown of DCAF7/wap reduces wing cell number, rescued by co-knockdown of dfoxo. |

CUL4B and DCAF7 form a CRL4B E3 ubiquitin ligase complex that binds MEN1 (menin), catalyzes its ubiquitylation, and promotes its proteasomal degradation; neddylation activates this pathway; DCAF7 knockdown restores MEN1 levels and re-sensitizes everolimus-resistant PanNET cells to mTOR inhibition, with effects reversible by simultaneous MEN1 knockdown. |
