Action potential-induced neurotransmitter release in presynaptic boutons involves coordinated actions of a large list of proteins that are associated directly or indirectly with membrane structures including synap-tic vesicles and plasma membranes. These proteins are often highly abundant in different synaptic bouton sub-compartments, and they rarely act alone. Instead, these proteins interact with each other forming intri-cate and distinct molecular complexes. Many of these complexes form condensed clusters on membrane surfaces. This review summarizes findings in recent years showing that many of presynaptic protein com-plex assemblies are formed via phase separation. These protein condensates extensively interact with lipid membranes via distinct modes, forming various mesoscale structures by different mode of organiza-tions between membraneless condensates and membranous organelles. We discuss that such mesos-cale interactions could have deep implications on mobilization, exocytosis, and retrieval of synaptic vesicles. (c) 2022 Elsevier Ltd. All rights reserved.
