Interaction of alpha-actinin, filamin and tropomyosin with F-actin

M G Zeece et al. Biochim Biophys Acta. .

Abstract

The abilities of alpha-actinin, filamin and tropomyosin to bind F-actin were examined by cosedimentation experiments. Results indicated that smooth muscle alpha-actinin and filamin can bind to actin filaments simultaneously with little evidence of competition. In contrast, tropomyosin exhibits marked competition with either filamin or alpha-actinin for sites on actin filaments.
