Vesicle-associated membrane protein (VAMP)-associated proteins (VAPs) are highly conserved endoplasmic reticulum (ER)-resident proteins that establish ER contacts with multiple membrane compartments in many eukaryotes. However, VAP-mediated membrane-tethering mechanisms remain ambiguous. Here, focusing on fission yeast ER-plasma membrane (PM) contact formation, using systematic interactome analyses and quantitative microscopy, we predict a non-VAP-protein direct binding-based ER-PM coupling. We  ...[more]
