Some biological processes such as vesicular transport are regulated by motifs that guide proteins to curved membranes. One of them is the ALPS (Amphipathic Lipid Packing Sensor) motif that recognizes packing defects induced by the convex curvature of the membrane. In this work, we combine molecular dynamics (MD) simulations and circular dichroism (CD) experiments to understand this phenomenon at the molecular level. MD simulations allowed us to characterize and quantify lipid packing defects. We show that packing defects caused by the membrane curvature are similar to those caused by the introduction of conical lipids in a flat bilayer composed of cylindrical lipids. By examining the interaction of the ALPS motif with a membrane containing ...
