Neuronal transport: myosins pull the ER

Whether class V myosins 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.
