Effects of alignment activity on the collapse kinetics of a flexible polymer

S Paul, S Majumder, SK Das, W Janke - Soft Matter, 2022 - pubs.rsc.org
The dynamics of various biological filaments can be understood within the framework of
active polymer models. Here we consider a bead-spring model for a flexible polymer chain …

Nucleation causes an actin network to fragment into multiple high-density domains

A Chandrasekaran, E Giniger, GA Papoian - Biophysical Journal, 2022 - cell.com
Actin networks rely on nucleation mechanisms to generate new filaments because
spontaneous nucleation is kinetically disfavored. Branching nucleation of actin filaments by …
