Target Name
Niemann-Pick C1-like protein 1
Gene Name
NPC1L1
Synonyms
Niemann-Pick C1 Like 1; NPC1L1
Target Type
Successful
Disease Hypercholesterolemia [ICD10: E78]
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 absorption. 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.
