CENP-T-W and CENP-S-X complexes coassemble to form a stable CENP-T-W-S-X heterotetramer with histone-fold domains that structurally resembles a nucleosome; the heterotetramer binds DNA and introduces supercoiling, and mutations disrupting heterotetramerization or DNA-protein contacts reduce DNA binding/supercoiling in vitro and compromise kinetochore assembly in vivo. |

The N-terminal disordered region of vertebrate CENP-T directly interacts with the RWD domain of Spc24/Spc25 (Ndc80 complex); CDK phosphorylation of CENP-T strengthens a cryptic hydrophobic interaction with Spc25 in a phospho-regulated manner that does not require direct recognition of the phosphorylated residue. The CENP-T–Ndc80 and Mis12–Ndc80 interactions are mutually exclusive, defining two parallel pathways for Ndc80 recruitment. |

The histone-fold protein Cnn1 (yeast CENP-T ortholog) is a direct centromere receptor of the Ndc80 complex; its conserved N-terminal peptide motif mediates stoichiometric binding to the Spc24-Spc25 domain; artificial tethering of Ndc80 through Cnn1 supports mini-chromosome segregation without a natural centromere. |

The CENP-T-W-S-X complex preferentially binds ~100 bp of linker DNA (not nucleosome-bound DNA), primarily as a (CENP-T-W-S-X)₂ dimer of tetramers, and unlike canonical nucleosomes induces positive rather than negative DNA supercoils; DNA-binding regions in CENP-T and CENP-W (but not CENP-S or CENP-X) are required for positive supercoiling and kinetochore targeting. |

CENP-T and CENP-C act in parallel but distinct pathways to recruit the KMN network: CENP-C recruits Ndc80 via KNL1 and Mis12, whereas CENP-T directly interacts with Ndc80, which in turn recruits KNL1/Mis12. Aurora B kinase promotes KMN recruitment to CENP-C, while CDK regulates KMN recruitment to CENP-T. |

The histone chaperone FACT (subunits Spt16/SSRP1) binds CENP-T/W; the C-terminal domain of Spt16 specifically binds the histone fold region of CENP-T/W. Depletion of Spt16 impairs CENP-T and CENP-W deposition at centromeres, and site-directed targeting of Spt16 alone is sufficient to drive de novo CENP-T accumulation at centromeres. |

Ndc80 binding to CENP-T is a two-step process: rapid initial association/dissociation at disordered N-terminal sites followed by a slower 'maturation' transition to stronger retention; this maturation kinetic barrier is markedly accelerated when CENP-T is clustered at high molecular density, explaining why clustered CENP-T recruits more Ndc80 than monomeric CENP-T, and the two Ndc80-binding sites on CENP-T exhibit distinct maturation rates. |

Depletion of CENP-T by siRNA in mouse oocytes increases CDH1/FZR1 levels, elevating APC-CDH1 activity and decreasing CCNB1, thereby attenuating MPF and severely compromising meiotic resumption (G2/M transition); these defects are rescued by CCNB1 overexpression or CDH1 knockdown, placing CENP-T upstream of CDH1 in regulating meiotic progression. |

In Xenopus egg extracts, CENP-T centromeric recruitment occurs in late interphase independently of DNA synthesis and precedes CENP-W recruitment (which occurs in mitosis); unlike CENP-C, CENP-T does not participate in CENP-A deposition; depletion of CENP-C reduces CENP-T at centromeres, but kinetochores can still assemble with reduced Ndc80/Mis12, supporting the existence of two parallel assembly pathways. |

Adaptive evolution of the CENP-T histone fold domain (DNA-binding region) in mice reduced centromere binding; introducing the histone fold domain from closely related species into mouse CENP-T (chimeric variants) increased centromere binding in oocytes and somatic cells; reduced binding by mouse CENP-T supports robust female gametogenesis, and the adaptation is independent of centromeric DNA sequence. |
