title: Polymerization of G-actin by caldesmon.
abstract: Electron microscopy of negatively stained samples indicates that caldesmon induces polymerization of G-actin into filaments. Polymerization takes place in a very low ionic strength solution and is accompanied by an increase of intensity of fluorescence of G-actin labelled with N-(1-pyrenyl)iodoacetamide. The effect of caldesmon is abolished by calmodulin in the presence of Ca2+.
