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.
We are excited to share our latest work in context of the colaborative research consortium 1430 @Crc1430. A preprint is available on bioRxiv (https://t.co/IqSKQcvIOR).
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
Errors during cell division can have dire consequences. If you are interested in understanding how kinetochores and the microtubule cytoskeleton work together to allow faithful chromosome segregation in mitosis apply to @LabWestermann@IMPRS_LM.

Excited to share my first first-author paper. Our work @hemmo_lab on lysosomal damage sensing and lysophagy initiation is out in @MolecularCell https://t.co/gvtInJAgKt. Here we show how cells triage damaged lysosomes for lysophagy via lipid-packing defect sensing by SPG20/Spartin
Excited to share our latest preprint, excellent work by Emily and @erinejenson! Extensive mutagenesis of the Ndc80c revealed a very busy 'interaction hub,' vital for Mps1 binding and competitive regulation of localization: https://t.co/YWxS6Tlx7L
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.
We are excited to share our latest preprint on BioRxiv (https://t.co/mQD0lJVvh2). 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.
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.
We have an opening for a #PhD Position. Apply now to join us @WWU Münster and work on an exciting #cryoEM project with focus on the interplay between pore forming toxins and receptors at the synaptic interface @SFB1438. RT appreciated
What a challenging but also exciting year! Three finished PhD theses, great publications and a nice Christmas party with all lab members. We wish you all Happy Holidays and a Happy New Year 🎁🎄🎊 #kinetochoreandmore#PhDone#HappyHolidays#glitter#celebration
