title: New insights into actin filament dynamics.
abstract: Great progress has been made in advancing an atomic-level model for F-actin. A growing body of data shows, however, that any picture of F-actin must take into account allosteric interactions within subunits, long-range cooperative effects that occur between subunits, and the fact that several conformations of the filament can exist.
