Novel function of Niemann‐Pick C1‐like 1 as a negative regulator of Niemann‐Pick C2 protein
Yoshihide Yamanashi, Tappei Takada, Jun‐Ichi Shoda, Hiroshi Suzuki – 16 November 2011 – The hepatic expression of Niemann‐Pick C1‐like 1 (NPC1L1), which is a key molecule in intestinal cholesterol absorption, is high in humans. In addition to NPC1L1, Niemann‐Pick C2 (NPC2), a secretory cholesterol‐binding protein involved in intracellular cholesterol trafficking and the stimulation of biliary cholesterol secretion, is also expressed in the liver. In this study, we examined the molecular interaction and functional association between NPC1L1 and NPC2.
