Both layers of the COPII coat come into view.
Anterograde transport in the early secretory pathway is mediated by COPII-coated vesicles. Stagg et al. (2008) have now visualized the double-layered COPII coat using electron cryomicroscopy, providing insight into how coats are assembled to accommodate cargo of different sizes.
