Happy to share our latest work showing that fungal cell fusion not only requires local cell wall digestion but also inhibition of cell wall repair! PAK-family kinases promote cell fusion irreversibility by preventing cell-wall repair doi.org/10.1016/j.cu... Led by @juliacoronasserna.bsky.social

Arp2/3-dependent actin assembly shapes endosomes and promotes intracellular trafficking in fission yeast

Endosomes serve as crucial sorting centers that streamline the distribution of cell surface proteins. The early endosome receives traffic from both th…

Super excited that this story by @borissieber.bsky.social is now on BioRxiv! For decades, we thought there was no MAPK scaffold for the ERK-like cascade that promotes sexual reproduction in fission yeast ... until Boris found it ! See the thread 👇 and enjoy the paper! doi.org/10.1101/2025...

New lab 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 @valthomas.bsky.social and nice collaboration with Andrea Picco and @kaksonen.bsky.social! www.biorxiv.org/content/10.1...
