  • Title: Caldesmon association with smooth muscle thin filaments isolated in the presence and absence of calcium.
    Author: Lehman W.
    Journal: Biochim Biophys Acta; 1986 Jan 23; 885(1):88-90. PubMed ID: 3942796.
    Abstract:
    Thin filaments isolated from chicken gizzard smooth muscle in either the presence or the absence of Ca2+ possess identical caldesmon contents. Hence, a 'flip-flop' mechanism, involving Ca2+-dependent association and dissociation of caldesmon and thin filaments, does not appear to operate in vivo and is an unlikely model for caldesmon function.
