MetabolomicsInositol triphosphate-triggered calcium release blocks lipid exchange at endoplasmic reticulum-Golgi contact sites
Vesicular traffic and membrane contact sites between organelles enable the exchange of proteins, lipids, and metabolites. Recruitment of membrane tethers to contact sites between the endoplasmic reticulum (ER) and the plasma membrane is often triggered by calcium. In contrast, we reveal here a funct...

MetabolomicsControlling mitochondrial membrane architecture via MIC60 determines viral replication to promote anti-viral immunity
Virus-infected cells often exhibit dramatic cellular changes accompanied by altered mitochondrial function. The contribution of factors shaping the inner mitochondrial membrane (IMM) and cristae architecture on viral replication is insufficiently understood. Single cell transcriptomics applying vesi...

ProteomicsPex3 promotes formation of peroxisome-peroxisome and peroxisome-lipid droplet contact sites
Peroxisomes are ubiquitous organelles that mediate central metabolic functions, such as fatty acid β-oxidation, as well as diverse tissue- and organism-specific processes. Membrane contact sites, regions of close apposition with other organelles for direct communication, are central to several aspec...

ProteomicsContact-ID, a new tool for profiling organelle-membrane contact sites, reveals regulatory proteins of mitochondrial-associated membrane formation
The mitochondria-associated membrane (MAM) has emerged as a cellular signaling hub regulating various cellular processes. However, its molecular components remain unclear owing to lack of reliable methods to purify the intact MAM proteome in a physiological context. Here, we introduce Contact-ID, a ...

ProteomicsIdentification of MOSPD2, a novel scaffold for endoplasmic reticulum membrane contact sites
Membrane contact sites are cellular structures that mediate inter-organelle exchange and communication. The endoplasmic reticulum (ER), which forms a network extending throughout the cytoplasm, possesses two known major tether proteins, named VAP-A and VAP-B, that allow its interaction with other or...

ProteomicsProfiling the LAM family of contact-site tethers provides mechanistic insights into their regulation and function
Membrane contact sites are molecular bridges between organelles that are sustained by tethering proteins and enable organelle communication. The endoplasmic reticulum (ER) membrane harbors many distinct families of tether proteins that enable the formation of contacts with all other organelles. One ...

ProteomicsER-Golgi membrane contact sites control the formation of plasma membrane lipid nanodomains required for anthrax intoxication
To promote infections, pathogens exploit host cell machineries including structural elements of the plasma membrane. Studying these interactions and identifying molecular players is an ideal way to gain insights into the fundamental biology of the host cell. Here, we used the anthrax toxin to screen...

MetabolomicsNPC1 regulates the distribution of phosphatidylinositol 4 kinases at Golgi and Lysosome membranes
Cholesterol and phosphoinositides (PI) are two critically important lipids that are found in cellular membranes and dysregulated in many disorders. Therefore, uncovering molecular pathways connecting these essential lipids may offer new therapeutic insights. We report that loss of function of lysoso...
