The earliest steps in autophagy are thought to include the budding of Atg16L-containing vesicles from the plasma membrane and their homotypic fusion to form a phagophore. Morozova et al. reveal a role for the membrane curvature-inducing protein Annexin A2 in the formation and fusion of these vesicles.
