WebThere are 2 general ways that cholesterol can move intracellularly, vesicular and nonvesicular. 3 Cholesterol is present in the membranes of intracellular vesicles that shuttle among compartments. Vesicular traffic typically requires an intact cytoskeleton, the tracks along which vesicles move, and ATP, providing energy for motor proteins. WebNPC intracellular cholesterol transporter 2.

Webits cholesterol esters are cleaved by acid lipase to release free cholesterol for cellular use (1). NPC2 protein is a small (25-kDa) globular protein (2, 3) that is thought to bind the choles-terol released from LDL and transfer it onto NPC1 (4–9), a 1278-residue protein with 13 transmembrane domains (10) (Fig. 1A). WebCNS hypomyelination is one of the pathological characteristics of Niemann–Pick Type C disease (NPC), a rare childhood-onset neurodegenerative disorder due to mutations of NPC1 (NPC intracellular cholesterol transporter 1) or NPC2 . Npc1-deficient mice display hypomyelination and delayed myelination caused by hampered OL maturation [202,203]. gin tonic e barbera

NPC1/SLC65A1 is an intracellular cholesterol transporter, which together with NPC2 (Uniprot ID P61916 ), allows the accumulation into the cytosol of cholesterol acquired from low density lipoproteins.
