Condensation of the fusion focus by the intrinsically disordered region of the formin Fus1 is essential for cell-cell fusion

I. Billault-Chaumartin, O. Muriel, L. Michon, S. G. Martin

This study shows that the intrinsically disordered region of Fus1 mediates condensation of the actin fusion focus, essential for yeast gamete fusion and preventing cell lysis.

The actin assembly requirements of the formin Fus1 to build the fusion focus

I. Billault-Chaumartin, L. Michon, C. A. Anderson, S. E. Yde, C. Suarez, J. Iwaszkiewicz, V. Zoete, D. R. Kovar, S. G. Martin

This study investigates how the nucleation and elongation rates of the formin Fus1 affect the formation of the actin fusion focus in fission yeast, showing that native rates are optimal for this structure.

Capping protein insulates Arp2/3-assembled actin patches from formins

I. Billault-Chaumartin, S. Martin

The paper shows that capping protein prevents formins from interfering with Arp2/3-assembled actin patches in fission yeast, maintaining their distinct identity and function.
