Does this mechanism ring a bell?.It is conceptually remarkably similar to how spindle poles form. It seems like the same principles apply to form cytoskeletal asters, whether based on actin or microtubules. #actin #microtubules #cytoskeleton.

Thus, by transporting Fus1 along actin filaments nucleated by other Fus1 dimers, the formin-myoxin V association underlies positive feedback convergence of actin filaments in the focus.

… and we find that the formin Fus1 is a myosin V cargo!. The movie shows coincident formin Fus1 (green) and myosin V Myo52 (magenta) signals converging together.

The cool finding is that the myosin V Myo52 (red), which transports secretory vesicles (purple) onto the fusion focus, dissociates from the pool of vesicles and joins the formin Fus1 (green) that assembles the focus. The two proteins physically associate…

We developed a 3-color live fluorescence-imaging method that allows mapping the position of protein pools with a precision of 8 nm. Applying it to the #actin fusion focus, an actin aster that underlies yeast cell fusion, we show stereotypical order and compaction of the structure

New preprint! High resolution mapping of the actin fusion focus reveals myosin V-dependent transport of formin for actin aster compaction. A very cool work led by @Vall_Thomas and collab with @g_trevize and @marko_kaksonen!.@sciences_UNIGE @Biologie_UNIGE

End-of-year read! The work of Melvin Bérard is now out in @PLOSBiology. Proteomic and phosphoproteomic analyses reveal that TORC1 is reactivated by pheromone signaling during sexual reproduction in fission yeast. @Biologie_UNIGE @MoCel_Geneva . See 👇.
On @BioRxiv, the PhD work of Melvin Bérard, with help of Laura Merlini: .TORC1 reactivation by pheromone signaling revealed by phosphoproteomics of fission yeast sexual reproduction. Enjoy the read!. Short summary below 👇. @MoCel_Geneva @Biologie_UNIGE.
