ncbi summary :
The protein encoded by this gene is a multi-pass membrane protein. It contains a conserved N-terminal Niemann-Pick C1 (NPC1) domain and a putative sterol-sensing domain (SSD) which includes a YQRL motif functioning as a plasma membrane to trans-Golgi network transport signal in other proteins. This protein takes up free cholesterol into cells through vesicular endocytosis and plays a critical role in the absorption of intestinal cholesterol. It also has the ability to transport alpha-tocopherol (vitamin E). The drug ezetimibe targets this protein and inhibits the absorption of intestinal cholesterol and alpha-tocopherol. In addition, this protein may play a critical role in regulating lipid metabolism. Polymorphic variations in this gene are associated with plasma total cholesterol and low-density lipoprotein cholesterol (LDL-C) levels and coronary heart disease (CHD) risk. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2009]
uniprot summary :
Function: Plays a major role in cholesterol homeostasis. Is critical for the uptake of cholesterol across the plasma membrane of the intestinal enterocyte. Is the direct molecular target of ezetimibe, a drug that inhibits cholesterol absorbtion. Lack of activity leads to multiple lipid transport defects. The protein may have a function in the transport of multiple lipids and their homeostasis, and may play a critical role in regulating lipid metabolism. Acts as a negative regulator of NPC2 and down-regulates its expression and secretion by inhibiting its maturation and accelerating its degradation. Ref.10 Ref.12. Subunit structure: Interacts with RAB11A, MYO5B and RAB11FIP2. Interaction with RAB11A, MYO5B and RAB11FIP2 is required for proper transport to the plasma membrane upon cholesterol depletion. Interacts with NPC2. Ref.11 Ref.12. Subcellular location: Apical cell membrane; Multi-pass membrane protein. Cell membrane; Multi-pass membrane protein . By similarity. Cytoplasmic vesicle membrane; Multi-pass membrane protein. Note: Subfractionation of brush border membranes from proximal enterocytes suggests considerable association with the apical membrane fraction. Exists as a predominantly cell surface membrane expressed protein . By similarity. According to Ref.8, localizes in a subcellular vesicular compartment rich in RAB5. Ref.8. Tissue specificity: Widely expressed. Expressed in liver. Also expressed in small intestine, pancreas, kidney, lung, pancreas, spleen, heart, gall bladder, brain, testis, stomach and muscle. Ref.1 Ref.2 Ref.8. Induction: Expression is decreased in Caco-2 cells upon PPARD activation. Ref.9. Post-translational modification: Highly glycosylated . By similarity. Polymorphism: Variations in NPC1L1 gene could be associated with non-response to ezetimibe treatment. Sequence similarities: Belongs to the patched family.Contains 1 SSD (sterol-sensing) domain.
