Retrotransposons can infect neighboring cells using a mechanism that relies on a small fusogen-like protein rather than on the envelope protein that is typically required for infection.

Radulovic et al. show that phosphatidylinositol 3-phosphate (PI3P), produced by the phosphatidylinositol 3-kinase PIK3C3, is formed on ER domains after lysosome damage. ER domain PI3P helps to recruit...

Animal cells extensively remodel their cytoskeleton during differentiation and can notably switch between two major motility modes: flagellum-based swimming and actin-based crawling. We previously sho...

Cytokinesis finalizes cell division by physically separating the daughter cells. After furrow ingression, the intercellular bridge (ICB) connecting th…

In cells, ESCRT-III is unique in mediating fission of membrane necks from inside, a process called reverse-topology fission. Yet, in vitro, the complex primarily assembles outside membrane necks and m...
