The N-terminus of CENP-T proteins interacts directly with the Ndc80 complex in the outer kinetochore. Importantly, the CENP-T-W complex does not directly associate with CENP-A, but with histone H3 in the centromere region. CENP-T and -W form a hetero-tetramer with CENP-S and -X and bind to a ~100 bp region of nucleosome-free DNA forming a nucleosome-like structure. The DNA-CENP-T-W-S-X complex is likely to be associated with histone H3-containing nucleosomes rather than with CENP-nucleosomes. This domain is the C-terminal histone fold domain of CENP-T, which associates with chromatin [2-3].

So far in vertebrates at least 15 centromere proteins have been identified, which are divided into several subclasses based on functional and biochemical analyses. These provide a platform for the formation of a functional kinetochore during mitosis. CENP-S is one that does not associate with the CENP-H-containing complex but rather interacts with CENP-X to form a stable assembly of outer kinetochore proteins that functions downstream of other components of the CCAN. This complex may directly allow efficient and stable formation of the outer kinetochore on the CCAN platform.

Macromolecular centromere-kinetochore complex plays a critical role in sister chromatid separation, but its complete protein composition as well as its precise dynamic function during mitosis has not yet been clearly determined. CENP-H contains a coiled-coil structure and a nuclear localisation signal. CENP-H is specifically and constitutively localised in kinetochores throughout the cell cycle. CENP-H may play a role in kinetochore organisation and function throughout the cell cycle [1]. This the C-terminus of the region, which is conserved from fungi to humans.
