Abstract		Exocytosis is a highly conserved and ubiquitous process of eukaryotic cells responsible for the release of signaling molecules into extracellular space. Exocytosis involves trafficking, docking and eventually fusion of vesicles, carrying various cargo, with the plasma membrane. Until recently, the membrane fusion was considered to be predominantly mediated by proteins such as SNAP receptors, Muncs and Rabs, where lipids only played a passive role. However, newer studies portray lipids differently. Not only do lipids have a significantly more important role in membrane merger as previously believed, they also appear to be critical for regulating the entire process of exocytosis. The purpose of this article is to highlight the importance of specific lipids and lipid-protein interactions in regulated release of neurotransmitters and hormones.
