Discovery of oxysterol-derived pharmacological chaperones for NPC1: implication for the existence of second sterol-binding site.

Abstract excerpt

Niemann-Pick type C1 (NPC1) is a polytopic endosomal membrane protein required for efflux of LDL-derived cholesterol from endosomes, and mutations of this protein are associated with Niemann-Pick disease type C, a fatal neurodegenerative disease. At least one prevalent mutation (I1061T) has been shown to cause a folding defect, which results in failure of endosomal localization, leading to a loss-of-function...
