Dynamin in Action (image) NIH/National Institute of General Medical Sciences Share Print E-Mail Caption Scientists studying dynamin use an artificial membrane (orange) to analyze the protein's action. In the first image, dynamin has squeezed the membrane to create two vesicle-like structures (lower right). In the second image, taken seconds later, dynamin has severed the membrane to release these structures.
