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.
摘要
研究了悬浮培养的小鼠成纤维细胞质膜对肌动蛋白聚合的影响。通过对肌动蛋白-膜混合物进行低剪切粘度测定，并结合用肌动蛋白解聚缓冲液提取膜的次数，发现至少两种分子量为220和94 kDa的多肽可能参与了肌动蛋白丝与质膜的相互作用。
