Whether class Vmyosins can work as point-to-point transporters in animal cells is highly debated. Myosin Va is now shown to function as a point-to-point transporter that pulls the endoplasmic reticulum (ER) into dendritic spines, with important consequences for dendritic development and cerebellar motor learning
目前已经证实，肌球蛋白 Va 可以作为一种点对点的转运蛋白，将内质网（ER）拉入微管棘突，这对树突发育和小脑运动学习有重要影响。至于 V 类肌球蛋白是否可以在动物细胞中作为点对点的转运体发挥作用，目前仍存在高度争议。
