Fragmentation and entanglement limit vimentin intermediate filament assembly

Q. D. Tran, V. Sorichetti, G. Pehau-Arnaudet, M. Lenz, C. Leduc

This study investigates vimentin intermediate filament assembly dynamics, revealing that fragmentation and entanglement influence assembly and disassembly, with fragmentation occurring independently of post-translational modifications.
