abstract：:Sterol accumulation in membranes blocks the exit of SCAP from the ER, preventing SREBP cleavage and reducing cholesterol synthesis. Sterols act through SCAP's sterol-sensing domain by an obscure mechanism. Here, we show that addition of cholesterol to ER membranes in vitro causes a conformational change in SCAP, detec...
