Abstract

Platelet talin nucleates actin assembly as we show here directly by using rhodamine-phalloidin labelling of actin filaments, Nucleation by talin still occurs after reconstitution into liposomal bilayers. This is also demonstrated directly after protein-lipid double labelling and light microscopic imaging. Talin, thus, is the first actin binding protein for which anchoring and nucleation of artin filament growth at lipid interfaces have been visualized.
