  • Title: Interaction of alpha-actinin, filamin and tropomyosin with F-actin.
    Author: Zeece MG, Robson RM, Bechtel PJ.
    Journal: Biochim Biophys Acta; 1979 Dec 14; 581(2):365-70. PubMed ID: 518922.
    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.
