The Elting Lab's first preprint was posted on BioRxiv! You can read the paper here. This project was a great team effort, led by graduate student Marc Begley, and also including contributions from undergraduates Elizabeth Davis and Grant Sherrill. Marc et al. ablated bundles of spindle microtubules called k-fibers that are responsible for attaching chromosomes to the mitotic spindle and ultimately for segregating them. This allows us to probe k-fiber mechanical cohesion and its molecular origin. In collaboration with Puck Ohi's group, we found that the kinesin-12 Kif15 is at least partially responsible for mechanically reinforcing k-fibers.
