Figure 2. Protein architecture of the human kinetochore.
A Cartoon of the organization of sister kinetochores on a human chromosome. The inter-centromeric localization of Aurora BIpl1 and MCAK is highlighted. B Top: Schematic displays a hypothetical spatial manifestation of the biochemical pathways of kinetochore assembly. Orange arrows indicate pathways of Ndc80 recruitment; grey dashed lines represent the microtubule. Note that CENP-TCnn1 recruits two Ndc80 molecules. Bottom: Cartoon of a hypothetical local architecture of the kinetochore-microtubule attachment in humans.
