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.

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.
