GCP-WD/NEDD1 is a subunit of the human γ-TuRC and acts as an attachment factor targeting the γ-TuRC to the centrosome and mitotic spindle; depletion of GCP-WD disperses the γ-TuRC from the centrosome and abolishes centrosomal microtubule nucleation, while leaving the γ-TuRC intact and able to bind microtubules. Mitotic phosphorylation of GCP-WD is separately required for γ-tubulin association with the spindle. |

NEDD1 is required for centrosomal targeting of the γ-TuRC and for centriole duplication; NEDD1 can target to the centrosome independently of γ-tubulin, but γ-tubulin cannot reach the centrosome without NEDD1. The C-terminal half of NEDD1 mediates binding to γ-TuRCs. |

Xenopus NEDD1 exists in a complex distinct from the γ-TuRC and is largely dispensable for targeting γ-tubulin to centrosomes in Xenopus egg extracts, but is required for microtubule organization in those extracts. |

FAM29A is regulated by Plk1, and Plk1, FAM29A, and NEDD1 form three separate complexes in vivo. Plk1 recruits FAM29A to spindle microtubules, which in turn targets NEDD1 to the spindle; Plk1 independently recruits NEDD1 to centrosomes. FAM29A controls partitioning of NEDD1 between centrosomes and spindle. |

NEDD1 directly binds γ-tubulin through a 62-residue C-terminal helical domain that forms a stable tetramer in solution; mutation of residues in this domain disrupts γ-tubulin binding and causes mis-localization of γ-tubulin away from the centrosome. |

NEDD1 is an essential component of acentriolar MTOCs in mouse oocytes, co-localizing with γ-tubulin and pericentrin in a pericentrin-dependent manner. NEDD1 knockdown reduces γ-tubulin at MTOCs, disrupts meiotic spindle structure, causes metaphase-I arrest via spindle checkpoint activation, and leads to high-frequency aneuploidy. |

Multiple phosphorylation sites in the S557–S574 region of NEDD1, near its γ-tubulin-binding domain, finely tune the NEDD1–γ-tubulin interaction and spindle assembly. S565–S574 phosphorylation inhibits γ-tubulin binding; additional S557–T560 mutations restore binding. CEP192 associates with NEDD1 and modulates its mitotic phosphorylation. |

Cryo-EM structures of NEDD1 bound to the human γ-TuRC reveal that the C-terminus of NEDD1 forms a tetrameric α-helical assembly contacting the lumen of the γ-TuRC cone, anchored to GCP4, GCP5, and GCP6 via MZT1–GCP3 subcomplexes, with its microtubule-binding WD40 domains oriented away from the complex. NEDD1 does not induce conformational changes in the γ-TuRC. CDK5RAP2 and NEDD1 can simultaneously associate with the open conformation of the γ-TuRC. |
