Abstract:
Certain microfilaments found in migratory single cells and in morphogenetically-active epithelial cells are shown to bind heavy meromyosin prepared from skeletal muscle. This ‘actin-like’ feature of the filaments is compatible with the hypothesis that such filaments are components of contractile systems in these cells.
