The limits of the most recent models of the actin filament are discussed. These model are generated without taking into account the effect of protein osmotic pressure and, in general, of the solvent conditions. As a result they do not provide a bone fide representation of the actin filament in vivo. A new 'fluttering wing' model is proposed which predicts that orientation of the monomers, intermonomer contacts and diameter of the actin filament are sensitive to protein osmotic pressure and to interaction with regulatory proteins.

Abstract
The limits of the most recent models of the actin filament are discussed. These model are generated without taking into account the effect of protein osmotic pressure and, in general, of the solvent conditions. As a result they do not provide a bone fide representation of the actin filament in vivo. A new 'fluttering wing' model is proposed which predicts that orientation of the monomers, intermonomer contacts and diameter of the actin filament are sensitive to protein osmotic pressure and to interaction with regulatory proteins.File in questo prodotto:
