A single Dictyostelium amoeba cell simultaneously labelled for the myosin-associated protein ElmoA (left) and the cytoskeleton protein F-actin (right). The bright spots on the right indicate sites near the outer cell membrane at which actin filaments form. The same regions are darker on the left, indicating that the ElmoA protein disappears from these regions. ElmoA is thought to be a negative regulator of actin filament formation and thus plays an important role in keeping the cell in shape.
