ON THE FRONT COVER: Conformation of actin subunits at the pointed end (top) and barbed end (bottom) of the actin filament. Gray subunits have a flat (F-actin-like) conformation while pink subunits have a twisted (G-actin-like) conformation. The pointed and barbed ends are capped by Tropomodulin (green) and CapZ (blue), respectively.
