DESCRIPTION

Also known as NPCL1_RAT, Npc1l1. 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 (By similarity). Lack of activity leads to multiple lipid transport defects. The protein may have a function in the transport of multiple lipids and their homeostasis. Acts as a negative regulator of NPC2 and down-regulates its expression and secretion by inhibiting its maturation and accelerating its degradation (By similarity). Interacts with RAB11A, MYO5B and RAB11FIP2. Interaction with RAB11A, MYO5B and RAB11FIP2 is required for proper transport to the plasma membrane upon cholesterol depletion (By similarity). Interacts with NPC2 (By similarity). Interacts with LIMA1 (By similarity).
