We are excited about this study as multiple studies had suggested that such an outer kinetochore receptor for Aurora B must exist. We feel it’s an important step towards understanding how Ipl1/Aurora B achieves tension-dependent substrate phosphorylation at the outer kinetochore.

Alex shows that the mutant is very sensitive to a reduction in Ipl1 activity. However, it can be rescue it by recruitment of active Ipl1 to KMN in vivo. Biochemically Ipl1-Sli15 binds reconstituted KMN via Spc105-Kre28 in vitro, the binding is counteracted by Ipl1 phosphorylation

Alex’ work describes a new mutant in the outer kinetochore KMN subunit Kre28/Zwint. This allele is intriguing because it resembles mutants in the tension-dependent error correction pathway such as ipl1, sli15 or sgo1.

Our work sheds new light in a mechanism how end-on attachment maturation can regulate the recruitment of Mps1 and shows the tight interconnection between error correction and the spindle assembly checkpoint.

The surface on Ndc80c that binds Mps1 also serves as interface for the Ipl1 regulated engagement of Dam1 at bi-oriented kinetochores. Dam1 competes with Mps1 in vitro and Dam1 mutants that mimic Ipl1 phosphorylation cannot displace Mps1 efficiently.

One conserved feature of the interaction is that it is negatively regulated byMps1 autophosphorylation. We mapped autophosphorylation sites in Mps1 and showed that phosphorylation contributes but is not sufficient for the release of Mps1 before anaphase.

In the manuscript, define a binding interface of Mps1 on Ndc80c, located on the backside of the CH-domains. Point mutations derived from the structure impair the Mps1:Ndc80c interaction in vitro and generate in Mps1 separation-of-function alleles in vivo.

We are excited to share our latest preprint on BioRxiv (. Together with @AndreaMusacchi1 we investigated the regulated recruitment of Mps1 to the budding yeast kinetochore and propose a model that puts Mps1 localization under indirect regulation of Ipl1.
