Abstract: | Effect of plasma membranes of murine fibroblasts cultivated in suspension on actin polymerization was studied. Using low shear viscometry of actin-membrane mixtures together with the number of extractions of membranes with actin depolymerizing buffers it was found that at least two polypeptides 220 and 94 kDa may be involved into the actin filaments-plasma membrane interaction. |
