Abstract
We examined the binding kinetics of intact talin and talin head and tail fragment with F‐actin at pH 7.0 and at low ionic strength. We observed by a transient kinetic method a fast followed by a slower binding process for intact talin and talin tail fragment with filamentous actin. The latter can be attributed to F‐actin cross‐linking and/or bundling, which was observed in cosedimentation assays as well as by low shear viscometry and electron microscopy [Zhang, J., Robson, R. M., Schmidt, J. M. & Stromer, M. H. (1996) Biochem. Biophys. Res. Commun. 218, 530–537]. This finding is supported by dynamic light scattering measurements, indicating changes in internal actin filament dynamics due to cross‐linking/bundling events with intact talin and talin and talin tail fragment. No binding of the talin head fragment with F‐actin was detected by either method.
