Abstract
Actinogelin, a regulatory protein of cell motility, enhanced gelation of actin filaments in the absence of calcium ions, only on standing still or with very low velocity gradients ( less than 0.1 s-1). The Ca2+-sensitive action of actinogelin on action filaments was dependent on a weak external force. In the presence of a micromolar level of Ca2+, actinogelin did not affect the network formation of actin filaments at all.
摘要
肌动凝胶蛋白是一种细胞运动的调节蛋白，在没有钙离子的情况下，仅在静止不动或极低速度梯度（小于0.1 s-1）时会增强肌动蛋白丝的凝胶化。肌动凝胶蛋白对肌动蛋白丝的钙离子敏感作用依赖于微弱的外力。在微摩尔浓度的钙离子存在时，肌动凝胶蛋白对肌动蛋白丝的网络形成完全没有影响。
