Cholesterol 71-82 NPC1 like intracellular cholesterol transporter 1 Homo sapiens 28-34 34407950-1 2021 Polytopic Niemann-Pick C1-like 1 (NPC1L1) plays a major role in intestinal absorption of biliary cholesterol, vitamin E (VE), and vitamin K (VK). Cholesterol 97-108 NPC1 like intracellular cholesterol transporter 1 Homo sapiens 34-40 34407950-2 2021 The drug ezetimibe inhibits NPC1L1-mediated absorption of cholesterol, lowering of circulating levels of low-density lipoprotein cholesterol. Cholesterol 58-69 NPC1 like intracellular cholesterol transporter 1 Homo sapiens 28-34 34407950-3 2021 Here, we report cryo-electron microscopy structures of human NPC1L1 (hNPC1L1) bound to either cholesterol or a lipid resembling VE. Cholesterol 94-105 NPC1 like intracellular cholesterol transporter 1 Homo sapiens 61-67 34407950-3 2021 Here, we report cryo-electron microscopy structures of human NPC1L1 (hNPC1L1) bound to either cholesterol or a lipid resembling VE. Cholesterol 94-105 NPC1 like intracellular cholesterol transporter 1 Homo sapiens 69-76 34407950-4 2021 These findings, together with functional assays, reveal that the same intramolecular channel in hNPC1L1 mediates transport of VE and cholesterol. Cholesterol 133-144 NPC1 like intracellular cholesterol transporter 1 Homo sapiens 96-103 34407950-6 2021 Mutation of tryptophan-347 lies in this region disrupts dimerization and the resultant monomeric NPC1L1 exhibits reduced efficiency of cholesterol uptake. Cholesterol 135-146 NPC1 like intracellular cholesterol transporter 1 Homo sapiens 97-103 34407950-7 2021 These findings identify the oligomeric state of hNPC1L1 as a target for therapies that inhibit uptake of dietary cholesterol and reduce the incidence of cardiovascular disease. Cholesterol 113-124 NPC1 like intracellular cholesterol transporter 1 Homo sapiens 48-55
