NEDD1 (GCP-WD) is a subunit of the human γ-TuRC and acts as an attachment factor for the γ-TuRC: depletion or inhibition of NEDD1 causes loss of γ-TuRC from the centrosome, abolishing centrosomal microtubule nucleation, while leaving the γ-TuRC intact. NEDD1 depletion also blocks mitotic chromatin-mediated microtubule nucleation and spindle assembly. Mitotic phosphorylation of NEDD1 is required for association of γ-tubulin with the spindle (but separately from centrosomal association). |

NEDD1 is required for centrosomal targeting of γ-TuRC: γ-TuRCs assemble normally without NEDD1 but cannot reach the centrosome. Conversely, NEDD1 targets to the centrosome independently of γ-tubulin. NEDD1 depletion impairs centriole duplication, as does depletion of γ-tubulin. The C-terminal half of NEDD1 mediates binding to γ-TuRC. |

FAM29A interacts with the NEDD1-γ-tubulin complex and recruits it to the mitotic spindle to promote MT-dependent MT amplification; NEDD1 is not required for centrosomal or chromatin-mediated nucleation per se, but its spindle recruitment by FAM29A is required for increasing MT mass and kinetochore fiber maturation. |

FAM29A (a Plk1 substrate) controls the partitioning of NEDD1 between the centrosome and the mitotic spindle: Plk1 recruits FAM29A to spindle MTs, which in turn targets NEDD1 to the spindle; Plk1 recruits NEDD1 to centrosomes via a direct Plk1-NEDD1 interaction independent of FAM29A. Plk1, FAM29A, and NEDD1 form three separate complexes in vivo. |

NEDD1 directly binds γ-tubulin through a 62-residue C-terminal helical domain that forms a stable tetramer in solution. Mutations in this domain that disrupt γ-tubulin binding cause mis-localization of γ-tubulin away from the centrosome. NEDD1 is likely oligomeric in vivo. |

NEDD1 co-localizes with γ-tubulin and pericentrin at MTOCs in mouse oocytes. NEDD1 depletion (siRNA) reduces γ-tubulin at MTOCs, disrupts meiotic spindle structure, causes metaphase-I arrest with spindle assembly checkpoint activation, and leads to 50% aneuploidy in oocytes that progress to metaphase-II. |

Nek9 phosphorylates NEDD1 on Ser377, driving recruitment of NEDD1 and thereby γ-tubulin to the centrosome in mitotic cells. This Nek9 function requires activation by Plk1-dependent phosphorylation of Nek9, but is independent of Nek6/Nek7, positioning Nek9 as an intermediary in the Plk1→Nek9→NEDD1(S377) pathway for centrosomal γ-tubulin recruitment during centrosome maturation. |

Aurora A interacts with and phosphorylates NEDD1 at Ser405. Ser405 phosphorylation is not required for centrosomal MT nucleation but is critical for MT nucleation in the vicinity of chromosomes and for RanGTP-dependent aster formation in Xenopus egg extracts, indicating Aurora A promotes chromatin-driven MT assembly specifically through NEDD1-S405 phosphorylation. |

Phosphorylation of NEDD1 in the S565-S574 region (near the γ-tubulin-binding domain) inhibits NEDD1 binding to γ-tubulin and causes spindle assembly defects equivalent to NEDD1 depletion; additional mutations in S557-T560 restore γ-tubulin binding and bipolar spindle assembly. CEP192 associates with NEDD1 and modulates its mitotic phosphorylation, thereby regulating spindle assembly. |

Aurora A-mediated phosphorylation of NEDD1 at Ser405 is required for microtubule nucleation during central spindle (midzone) assembly in late mitosis; expression of a phosphomimetic NEDD1-S405 isoform restores midzone MT nucleation when Aurora A is inhibited. |

PLK4 phosphorylates NEDD1 at Ser325, which directly promotes NEDD1 binding to SAS-6 and recruiting SAS-6 to the centrosome. Phosphomimetic NEDD1-S325E promotes cartwheel assembly and daughter centriole biogenesis initiation, whereas non-phosphorylatable S325A abolishes these initiations. NEDD1 thus acts on the PCM layer to initiate centriole duplication under PLK4 regulation. |

Cryo-EM structure of NEDD1 bound to human γ-TuRC reveals that the C-terminus of NEDD1 forms a tetrameric α-helical assembly that contacts the lumen of the γ-TuRC cone, is anchored to GCP4, 5 and 6 via MZT1 & GCP3 subcomplexes, and orients its N-terminal WD40 (microtubule-binding) domains away from the complex. NEDD1 does not induce conformational changes in the γ-TuRC, and the γ-TuRC can simultaneously bind both NEDD1 and CDK5RAP2 in the open conformation. NEDD1 mutants unable to pull-down γ-tubulin biochemically validated the structural model. |

NEDD1's WD40 β-propeller domain directly binds the V-junction of Augmin (plant ortholog, structurally conserved principle); NEDD1 binding to Augmin enhances Augmin's antiparallel dimerization, and cooperativity between NEDD1 WD40 and the Augmin dual CH domains may regulate MT lattice binding to anchor γ-TuRC for branched MT nucleation. |

In developing mouse brain neurons, GCP-WD/NEDD1 and CDK5RAP2 are lost from centrosomes during neuron maturation, coinciding with loss of centrosomal γ-tubulin and cessation of centrosomal MT nucleation activity; MT nucleation subsequently occurs within dendrites rather than at the centrosome. |
