1·It occurs as a monomer, G-actin, a globular protein, and in living cells as a polymer, F-actin, which resembles two strings of beads twisted around each other into thin filaments.

以单体、球型肌动蛋白的形式出现，为一种球状蛋白质；在活体细胞内以聚合物、丝肌动蛋白的形式出现，像两串彼此缠绕拧成一条细丝的珠子。

2·Many small G proteins associate with the regulation of the actin cytoskeleton, and CAP is a link molecule between signaling pathways and subsequent alterations in the cytoskeleton.

许多小分子G蛋白参与细胞骨架调节，CAP蛋白是两者间重要连接分子。
