On the mechanics of the actin filament: the linear relationship between stiffness and yield strength allows estimation of the yield strength of thin filament in vivo

J Muscle Res Cell Motil. 2004;25(1):103-5. doi: 10.1023/b:jure.0000021348.10678.f9.

Abstract

Comparison of the behaviour of actin filaments either modified with tetramethylrhodamine iodoacetamide or decorated with tetramethylrhodamine-phalloidin or with tropomyosin or with myosin subfragment 1 shows that, in all the cases, yield strength is linearly related to stiffness.
