Platelet talin binds to actin in vitro and hence is an actin binding protein. By four different non‐interfering assay conditions (fluorescence, fluorescence recovery after photobleaching, (FRAP), dynamic light scattering and DNase‐I inhibition) we show that talin promotes filament nucleation, raises the filament number concentration and increases the net rate of actin polymerization but has no inhibitory effect on filament elongation. Binding of talin to actin occurs at a maximal molar ratio of 1:3 as determined by fluorescencetitration under G‐buffer conditions. The overall binding constant was ≈ 0.25 μM.
