The association between murine fibroblast L plasma membranes and actin was studied by means of low-shear viscometry of membrane-actin mixtures. Membrane fractions of 3 genetically related sublines of L cells were used differing in cytoskeleton structural organization. The suspension cell subline LS membranes showed actin gelatin activity. On the contrary, the membranes of monolayer cell sublines L-929 and LSM were seen to bind actin and to cause decrease in viscosity. Possible mechanisms of such interactions are discussed.
