鬼笔环肽是一种双环七肽毒素，特异性结合在F-肌动蛋白亚基之间的界面上，将相邻的亚基锁定在一起。鬼笔环肽与肌动蛋白丝的结合比与肌动蛋白单体的结合要紧密得多，从而导致肌动蛋白亚基从丝端解离的速率常数降低，因此通过防止丝解聚而基本稳定了肌动蛋白丝，终，发现鬼笔环肽抑制F-肌动蛋白的ATP水解活性。

鬼笔环肽的性质是研究F-肌动蛋白在细胞中分布的有用工具，方法是用荧光类似物标记鬼笔环肽并将其用于染色肌动蛋白丝以进行光学显微镜检查。鬼笔环肽的荧光衍生物已被证明在寻找活细胞或固定细胞中的肌动蛋白丝以及体外观察单个肌动蛋白丝方面非常有用。荧光鬼笔环肽衍生物已被用作高分辨率研究肌动蛋白网络的重要工具。AAT Bioquest可以提供多色成像应用的鬼笔环肽。
