CEP97 recruits CP110 to centrosomes; depletion of CEP97 causes CP110 disappearance from centrosomes, spindle defects, and polyploidy. Loss of CEP97 or CP110 promotes primary cilia formation in growing cells, while enforced expression of CP110 in quiescent cells suppresses ciliogenesis, establishing that CEP97 and CP110 collaborate to inhibit a ciliogenesis program. |

CP110 interacts with CEP290 in a complex separable from other CP110 complexes; this CEP290-CP110 interaction is required for CP110-mediated suppression of primary cilia formation. CEP290 also interacts with Rab8a, and CEP290 depletion disrupts Rab8a localization to centrosomes/cilia. |

Kif24, a kinesin-13 subfamily motor protein, specifically interacts with CP110 and CEP97 at the mother centriole, preferentially localizing to mother centrioles. Loss of Kif24 causes CP110 disappearance from mother centrioles in cycling cells and aberrant cilia assembly. Kif24 can bind and depolymerize microtubules in vitro and specifically remodels centriolar microtubules when ectopically expressed. |

In cytotoxic T lymphocytes (CTLs), CP110 and CEP97 remain associated with the mother centriole and neither axoneme nor transition zone ciliary structures form, demonstrating that CP110/CEP97 retention at the mother centriole prevents ciliogenesis during centrosome docking at the immunological synapse. |

MPP9 is recruited by KIF24 to the distal end of the mother centriole where it forms a ring-like structure and directly binds CEP97 to recruit the CP110-CEP97 complex. Upon TTBK2-mediated phosphorylation of MPP9 at the onset of ciliogenesis, MPP9 is degraded via the ubiquitin-proteasome system, facilitating removal of CP110 and CEP97 from the mother centriole distal end. |

In Drosophila, Cep97 is essential for formation of full-length centrioles and for ciliogenesis, acting as part of a protective cap at the centriole distal end. The microtubule deacetylase Sirt2 was identified as a Cep97 interactor; both Sirt2 deletion and Atat1 (acetylase) deletion impair centriole integrity, indicating Cep97 cooperates with the microtubule acetylation machinery to maintain centriole stability. |

Dyrk1a phosphorylates CEP97, which promotes recruitment of Polo-like kinase 1 (Plk1) to multiciliated cells. CEP97 and Dyrk1a coordinate with Plk1 to promote Separase function for centriole disengagement during multiciliogenesis; knockdown of CEP97 or Dyrk1a disrupts cilia formation and centriole disengagement, rescued by Separase overexpression. |

LUBAC generates linear ubiquitin chains specifically on CP110, and a pre-mRNA splicing factor PRPF8 at the distal end of the mother centriole acts as receptor for these linear ubiquitin chains to facilitate CP110 (and consequently CEP97) removal at the initial stage of ciliogenesis. |

ENKD1 competes with CEP97 for binding to CP110; depletion of ENKD1 enhances the CP110-CEP97 interaction and detains CP110 at the mother centriole, inhibiting ciliogenesis. Simultaneous knockdown of ENKD1 and CP110 reverses the ciliogenesis defect, placing ENKD1 as a promoter of CP110 removal by competing with CEP97. |

In Drosophila embryos, CP110 and Cep97 form a complex at the distal end of centrioles whose levels oscillate with the cell cycle, entrained by the Cdk-Cyclin oscillator. Changing CP110/Cep97 levels alters Plk4 oscillation and cartwheel growth at the proximal end, revealing unexpected crosstalk between distal-end capping factors and proximal-end cartwheel assembly. |

During cerebellar granule cell differentiation, mother centrioles in maturing neurons recruit CEP97 (centriole cap complex) while cilia disassemble and cells permanently lose the ability to re-ciliate, indicating that CEP97 re-capping of docked mother centrioles prevents cilia regrowth in post-mitotic neurons. |
