Abstract:Membrane contact sites (MCSs) are regions in cells where membranes of two organelles are in close apposition. MCSs are proposed to facilitate non‐vesicular trafficking of lipids. Lipid transfer proteins (LTPs) are one of the most commonly‐found components in the MCS system and are speculated to mediate lipid transfer between membranes. However, both the biological functions of MCSs and the functional role of LTP in MCSs remain largely elusive. Herein, we examine in detail a previously‐proposed MCSs model, the … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
