1 Ergosterol interacts with Sey1p to promote atlastin-mediated endoplasmic reticulum membrane fusion in Saccharomyces cerevisiae. Ergosterol dynamin-like GTPase SEY1 Saccharomyces cerevisiae S288C
2 Although ergosterol, the major sterol in yeast, is essential for fusion of Sey1p (yeast atlastin)-containing liposomes with an ER-mimicking lipid composition, fusion of phosphatidylcholine/phosphatidylserine liposomes does not require sterols. Ergosterol dynamin-like GTPase SEY1 Saccharomyces cerevisiae S288C
