Ena/VASP processive elongation is modulated by avidity on actin filaments bundled by the filopodia crosslinker fascin

A. J. Harker, H. H. Katkar, T. C. Bidone, F. Aydin, G. A. Voth, D. A. Applewhite, D. R. Kovar

This study shows Ena/VASP tetramers enhance processivity on fascin-bundled actin filaments through avidity, increasing run length with more filaments and arms.

Insights into the cooperative nature of ATP hydrolysis in actin filaments

H. H. Katkar, A. Davtyan, A. E. P. Durumeric, G. M. Hocky, A. C. Schramm, E. M. De La Cruz, G. A. Voth

This paper develops a multiscale UCG model to study ATP hydrolysis and Pi release in actin filaments, showing cooperativity affects filament dynamics near critical monomer concentrations.
