CEP97 was purified as part of a complex with CP110 and directly 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 cycling cells, and enforced CP110 expression suppresses cilia assembly in quiescent cells, establishing CEP97 and CP110 as collaborative inhibitors of ciliogenesis. |

Kif24, a kinesin-13 subfamily motor protein, specifically interacts with CP110 and CEP97 at centrosomes, preferentially localizes to mother centrioles, and is required for maintaining CP110 at mother centrioles in cycling cells. Kif24 can bind and depolymerize microtubules in vitro, and its ectopic expression specifically remodels centriolar microtubules. |

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

In Drosophila, Cep97 is essential for formation of full-length centrioles in multiple tissues and interacts with the microtubule deacetylase Sirt2; both Sirt2 deletion and Atat1 (acetylase) deletion affect centriole size, supporting a model whereby Cep97 acts as a protective cap cooperating with the microtubule acetylation machinery to maintain centriole stability. Unlike in vertebrates, Drosophila Cep97 is only transiently removed from basal bodies and its loss strongly impairs ciliogenesis. |

CEP97 interacts with Dyrk1a kinase in Xenopus multiciliated cells; Dyrk1a phosphorylates CEP97, which promotes recruitment of Plk1, a critical regulator of centriole disengagement that cooperates with Separase for centriole separation during multiciliogenesis. Knockdown of either CEP97 or Dyrk1a disrupts cilia formation and centriole disengagement, rescued by Separase overexpression. |

LUBAC-mediated linear ubiquitination of CP110 is required for CP110 removal from the mother centriole, with PRPF8 acting as a receptor for linear ubiquitin chains at the distal mother centriole. CEP97, as part of the CP110-CEP97 complex, is targeted by this LUBAC-dependent mechanism. |

In Drosophila embryos, CP110 and CEP97 form a complex at the distal end of centrioles whose levels oscillate as centriole MTs grow; altering CP110 or Cep97 levels perturbs the Plk4 oscillation and cartwheel growth at the proximal end, revealing crosstalk between distal-end cap proteins and proximal-end centriole growth machinery. |

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

CDK1 phosphorylates centriolar proteins including Centrobin at the centrosome, and CEP97-CCP110 restricts Centrobin localization to centrioles; CDK1-dependent phosphorylation suppresses Centrobin's centriole elongation activity. CEP97-CCP110 and CDK1 cooperatively restrict centriole elongation by inhibiting Centrobin via distinct mechanisms. Removal of CEP97 during mouse development causes centriole overelongation, impaired ciliogenesis, attenuated Hedgehog signaling, and disrupted heart development. |
