Regeneration of actin filament branches from the same Arp2/3 complex

F. Ghasemi, L. Cao, M. Mladenov, B. Guichard, M. Way, A. Jegou, G. Romet-Lemonne

The paper shows that Arp2/3 complex can re-nucleate actin branches without NPF activation after debranching, suggesting a self-repair mechanism for actin networks.

Direct observation of the conformational states of formin mDia1 at actin filament barbed ends and along the filament.

J. Maufront, B. Guichard, L. Y. cao, A. Di Cicco, A. JEGOU, G. Romet-Lemonne, A. Bertin

This study uses electron microscopy to directly observe two conformations of mDia1 FH2 domains interacting with actin filament barbed ends, supporting the stair stepping model.

Actin filament oxidation by MICAL1 suppresses protections from cofilin-induced disassembly

H. Wioland, S. Fremont, B. Guichard, A. Echard, A. JEGOU, G. Romet-Lemonne

This study shows that MICAL1-induced actin filament oxidation enhances cofilin binding and severing, bypassing the need for cofilin activation and overcoming tropomyosin protection.

Geometrical constraints greatly hinder formin mDia1 activity

E. L. Suzuki, B. Guichard, G. Romet-Lemonne, A. Jegou

This study shows that geometrical constraints significantly reduce mDia1 formin elongation rates and processivity when filaments are bundled or cross-linked.

Modulation of formin processivity by profilin and mechanical tension

M. Kerleau, L. Cao, E. Suzuki, H. Wioland, S. Jouet, B. Guichard, M. Lenz, G. Romet-Lemonne, A. Jegou

This study investigates how profilin and mechanical tension modulate formin mDia1 processivity by altering dissociation rates from actin filaments.
