产品介绍 :   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].

Function:

Involved in the intracellular trafficking of cholesterol. May play a role in vesicular trafficking in glia, a process that may be crucial for maintaining the structural and functional integrity of nerve terminals.

Subunit:

Interacts with TMEM97.

Subcellular Location:

Late endosome membrane; Multi-pass membrane protein. Lysosome membrane; Multi-pass membrane protein.

Post-translational modifications:

Glycosylated.

DISEASE:

Defects in NPC1 are the cause of Niemann-Pick disease type C1 (NPC1) [MIM:257220]. A lysosomal storage disorder that affects the viscera and the central nervous system. It is due to defective intracellular processing and transport of low-density lipoprotein derived cholesterol. It causes accumulation of cholesterol in lysosomes, with delayed induction of cholesterol homeostatic reactions. Niemann-Pick disease type C1 has a highly variable clinical phenotype. Clinical features include variable hepatosplenomegaly and severe progressive neurological dysfunction such as ataxia, dystonia and dementia. The age of onset can vary from infancy to late adulthood. An allelic variant of Niemann-Pick disease type C1 is found in people with Nova Scotia ancestry. Patients with the Nova Scotian clinical variant are less severely affected.

Similarity:

Belongs to the patched family.

Contains 1 SSD (sterol-sensing) domain.

尼曼匹克病-神经磷沉积性疾病，主要是由于神经磷脂酶（sphingomyelinase）缺乏所致，神经鞘磷脂酶（sphingomyelinase）缺乏致神经鞘磷脂代谢障碍。导致后者蓄积在单核巨噬细胞系统内，出现肝、脾肿大，中枢神经系统退行性变。神经鞘磷脂是由N-酰鞘氨醇与一个分子的磷酸胆硷（phosphocholine）在C1、部位连接而成，神经鞘磷脂来源于各种细胞膜和红细胞基质等。在细胞代谢衰老过程中被巨噬细胞吞噬，神经磷脂酶缺少后，全身神经鞘磷脂代谢紊乱，神经磷脂沉积在单核-巨噬细胞系统和神经组织细胞中。
