NPC1
Niemann-Pick disease, type C1 (NPC1) is a membrane protein that mediates intracellular cholesterol trafficking in mammals. In humans it is encoded by the ''NPC1'' gene (chromosome location 18q11).〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=4864 )〕 == Function ==
NPC1 was identified as the gene that when mutated, results in Niemann-Pick disease, type C. Niemann-Pick disease, type C is a rare neurovisceral lipid storage disorder resulting from autosomal recessively inherited loss-of-function mutations in either NPC1 or NPC2. This disrupts intracellular lipid transport, leading to the accumulation of lipid products in the late endosomes and lysosomes. Approximately 95% of NPC patients are found to have mutations in the NPC1 gene. NPC1 encodes a putative integral membrane protein containing sequence motifs consistent with a role in intracellular transport of cholesterol to post-lysosomal destinations.〔
