Function
NDC80_YEAST Acts as a component of the essential kinetochore-associated NDC80 complex, which is involved in chromosome segregation and spindle checkpoint activity.[1] [2] [3] [4]
Publication Abstract from PubMed
The heterotetrameric Ndc80 complex establishes connectivity along the principal longitudinal axis of a kinetochore. Its two heterodimeric subcomplexes, each with a globular end and a coiled-coil shaft, connect end-to-end to create a approximately 600 A long rod spanning the gap from centromere-proximal structures to spindle microtubules. Neither subcomplex has a known function on its own, but the heterotetrameric organization and the characteristics of the junction are conserved from yeast to man. We have determined crystal structures of two shortened ("dwarf") Ndc80 complexes that contain the full tetramer junction and both globular ends. The junction connects two alpha-helical coiled coils through regions of four-chain and three-chain overlap. The complexity of its structure depends on interactions among conserved amino-acid residues, suggesting a binding site for additional cellular factor(s) not yet identified.
