		+	== Function ==
		+	[https://www.uniprot.org/uniprot/CENPK_YEAST CENPK_YEAST] Component of the kinetochore, a multiprotein complex that assembles on centromeric DNA and attaches chromosomes to spindle microtubules, mediating chromosome segregation and sister chromatid segregation during meiosis and mitosis. Component of the inner kinetochore constitutive centromere-associated network (CCAN), which serves as a structural platform for outer kinetochore assembly.<ref>PMID:9987135</ref>

		+	== Publication Abstract from PubMed ==
		+	Kinetochores are large multi-subunit complexes that attach centromeric chromatin to microtubules of the mitotic spindle, enabling sister chromatid segregation in mitosis. The inner kinetochore constitutive centromere associated network (CCAN) complex assembles onto the centromere-specific Cenp-A nucleosome (Cenp-ANuc), thereby coupling the centromere to the microtubule-binding outer kinetochore. CCAN is a conserved 14-16 subunit complex composed of discrete modules. Here, we determined the crystal structure of the Saccharomyces cerevisiae Cenp-HIKHead-TW sub-module, revealing how Cenp-HIK and Cenp-TW interact at the conserved Cenp-HIKHead-Cenp-TW interface. A major interface is formed by the C-terminal anti-parallel alpha-helices of the histone fold extension (HFE) of the Cenp-T histone fold domain (HFD) combining with alpha-helix H3 of Cenp-K to create a compact three alpha-helical bundle. We fitted the Cenp-HIKHead-TW sub-module to the previously determined cryo-EM map of the S. cerevisiae CCAN-Cenp-ANuc complex. This showed that the HEAT repeat domain of Cenp-IHead and C-terminal HFD of Cenp-T of the Cenp-HIKHead-TW sub-module interact with the nucleosome DNA gyre at a site close to the Cenp-ANuc dyad axis. Our structure provides a framework for understanding how Cenp-T links centromeric Cenp-ANuc to the outer kinetochore through its HFD and N-terminal Ndc80-binding motif, respectively.
