Aurora B-INCENP Localization at Centromeres/Inner Kinetochores Is Required for Chromosome Bi-orientation in Budding Yeast (Current Biology)

García-Rodríguez et al. show that the COMA inner kinetochore sub-complex physically interacts with Sli15, recruits Ipl1-Sli15 to the inner kinetochore, and promotes chromosome bi-orientation, independently of Bir1, in budding yeast. They conclude that localization of Ipl1-Sli15 at centromeres/inner kinetochores is required for bi-orientation.
