CEP164 localizes to the distal appendages of mature centrioles (mother centriole), as determined by immunogold electron microscopy, and is indispensable for primary cilium formation. Unlike subdistal appendage proteins ninein and Cep170, CEP164 persists at centrioles throughout mitosis, and its localization is mutually independent of ninein/Cep170 during interphase. |

CEP164 (KIAA1052) interacts with both ATR and ATM kinases, is phosphorylated at Ser186 by ATR/ATM in vitro and in vivo upon replication stress, UV, and ionizing radiation, and functions as a mediator in the DNA damage response. MDC1 knockdown severely reduces Ser186 phosphorylation, and CEP164 knockdown diminishes DNA damage-induced phosphorylation of RPA, H2AX, MDC1, CHK2, and CHK1 (but not NBS1), and causes G2/M checkpoint defects. |

Upon UV irradiation, CEP164 interacts with XPA (Xeroderma pigmentosum group A) in a UV-dependent manner; CEP164 binds to amino acids 4–97 of XPA. XPA is required for recruitment of CEP164 to cyclobutane pyrimidine dimer (CPD) sites. CEP164 knockdown compromises cell survival upon UV damage and impairs UV-induced CHK1 phosphorylation. |

Upon induced DNA damage, CEP164 co-localizes to nuclear foci positive for TIP60 (an ATM activator) together with ZNF423 and NPHP10. CEP164 knockdown causes sensitivity to DNA damaging agents. Zebrafish cep164 knockdown results in dysregulated DDR and a nephronophthisis-related ciliopathy phenotype. |

CEP164 physically interacts with INPP5E (inositol polyphosphate-5-phosphatase E) and participates in a functional network with ARL13B, INPP5E, and PDE6D for ciliary targeting of INPP5E. This network is distinct from those defined by NPHP and MKS proteins. |

CEP164 recruits TTBK2 (Tau tubulin kinase 2) to the mother centriole to trigger ciliogenesis. CEP164 is a likely physiological substrate of TTBK2. Complex formation between CEP164 and TTBK2 is mediated by mapped interaction domains, and is essential for TTBK2 recruitment to basal bodies. Ciliogenesis can be rescued in CEP164-depleted cells by chimeric proteins fusing TTBK2 to the C-terminal centriole-targeting domain of CEP164. TTBK2 acts upstream of CEP164 to contribute to distal appendage assembly. |

CEP164 is essential for TTBK2 centriolar localization via a proline-rich motif on TTBK2 (not via SxIP/EB1 motifs). TTBK2 non-Cep164-binding mutants fail to rescue CP110 removal and ciliogenesis in TTBK2-depleted cells. TTBK2 can phosphorylate CEP164 and Cep97, and TTBK2 kinase activity inhibits the CEP164–Dishevelled-3 interaction. |

CEP164 knockdown promotes cells to accumulate in S-phase and causes cell cycle acceleration, apoptosis, and epithelial-to-mesenchymal transition. These effects can be rescued by wild-type CEP164 but not disease-associated CEP164 mutants. Overexpression of dominant-negative CEP164 Q525X also induces EMT and pro-fibrotic gene upregulation. |

NEGATIVE FINDING: Conditional depletion of CEP164 in DT40 cells (auxin-inducible degron) caused no increase in sensitivity to ionising or UV irradiation. Disruption of CEP164 in human RPE cells blocked primary cilium formation but did not affect proliferation or responses to ionising/UV irradiation. No nuclear localization of CEP164 was detected by immunofluorescence or analysis of multiple tagged forms of CEP164. These data suggest CEP164 is not required for the DNA damage response. |

CEP164 is required for multiciliogenesis via regulation of small vesicle recruitment, ciliary vesicle formation, and basal body docking. CEP164 is necessary for proper recruitment of Chibby1 (Cby1) and its binding partners FAM92A and FAM92B to the ciliary base in multiciliated cells. CEP164 controls ciliary targeting of membrane-associated proteins including Rab8, Rab11, and Arl13b. Unlike in primary ciliogenesis, CEP164 is dispensable for IFT component recruitment to multicilia. |

Collecting duct-specific deletion of Cep164 in mice abolishes primary cilia from collecting duct epithelium and leads to rapid postnatal cyst growth driven by tubular hyperproliferation. Administration of the cell cycle inhibitor roscovitine blocked cyst growth, confirming cell cycle dysregulation as the primary cystogenesis mechanism. |

CEP164 recruits Chibby1 (Cby1) to basal bodies to facilitate basal body docking and multiciliogenesis in efferent ducts. FoxJ1-Cre;CEP164fl/fl mice show loss of multicilia in efferent ducts with accumulation of undocked basal bodies in the cytoplasm. The apical localization of Cby1 and the transition zone marker NPHP1 is severely diminished, indicating basal body docking defects. |

Deletion of CEP164 post-ciliogenesis in rod photoreceptors impairs intraflagellar transport (IFT): IFT components IFT88, IFT57, and IFT140 were reduced at basal body and ciliary tip. CEP164 is also required for basal body docking to the apical membrane; retina-specific KO at embryonic stage prevents connecting cilium and outer segment formation. CEP164 is key for recruitment and stabilization of IFT-B particles at the basal body/connecting cilium. |

CEP164 physically interacts with GLI2 transcription factor at the mother centriole. The GLI2-binding region of CEP164, when ectopically expressed, reduces centriolar GLI2 localization and enhances expression of Hedgehog target genes, both in cells with and without primary cilia, demonstrating a cilia-independent role for CEP164 in controlling Hh signaling at the mother centriole. |

CEP164 homodimerizes via its central coiled-coil region, which is required for its mother centriole localization and subsequent TTBK2 recruitment. TTBK2 kinase activity plus its interaction with CEP164 are both required for recruitment of IFT-A, IFT-B, and dynein-2 complexes to, and removal of CP110 from, the mother centriole. CP110 removal is not always coupled with IFT protein recruitment. |

These vesicles subsequently fuse to form tubular C-shaped and toroidal membrane intermediates that organize into the ciliary vesicle. |
