The study presents cryo-electron microscopy structures of human autophagy-related protein (ATG) 2A in complex with WD-repeat protein interacting with phosphoinositides 4 (WIPI4) and the ATG2A–WIPI4–ATG9A complex, providing insights into spatially coupled lipid transport and re-equilibration during autophagosome formation.
