NPC1 - NPC intracellular cholesterol transporter 1 Gene
Also Known as NPC; POGZ; SLC65A1
Species: Homo sapiens
About NPC1
This gene has 14 transcripts (splice variants), 210 orthologues, 10 paralogues and is associated with 7 phenotypes. Ubiquitous expression in adrenal (RPKM 13.9), brain (RPKM 10.0) and 24 other tissues.
Summary
This gene encodes a large protein that resides in the limiting membrane of endosomes and lysosomes and mediates intracellular Cholesterol trafficking via binding of Cholesterol to its N-terminal domain. It is predicted to have a cytoplasmic C-terminus, 13 transmembrane domains, and 3 large loops in the lumen of the endosome - the last loop being at the N-terminus. This protein transports low-density lipoproteins to late endosomal/lysosomal compartments where they are hydrolized and released as free Cholesterol. Defects in this gene cause Niemann-Pick type C disease, a rare autosomal recessive neurodegenerative disorder characterized by over accumulation of Cholesterol and glycosphingolipids in late endosomal/lysosomal compartments.[provided by RefSeq, Aug 2009]
