β-Escin is a well-known saponin derived from the horse chestnut tree. Saponins, including escin, exhibit a wide range of biological activities, among which membrane-modifying activity is particularly notable. The latter is key to understanding the molecular mechanisms underlying escin’s biological effects, including its antiviral properties. For example, altering membrane properties can strongly influence the life cycle of enveloped viruses such as SARS-CoV-2 by modulating the activity of its envelope protein (E protein). In the present paper, we studied the localization of both escin and the E protein transmembrane domain (ETM) in model membranes with different lipid compositions. We demonstrated that escin can alter ETM localization in membranes containing the negatively charged lipid DMPS, and that escin is also capable of extracting cholesterol from model lipid membranes.
