ABSTRACT
The membrane transporter ATP-binding cassette transporter A1 (ABCA1) has been shown to be the rate-limiting step in the initial formation of plasma high-density lipoprotein (HDL) particles. The mechanisms of action of ABCA1, including its role in the vesicular transport of lipids to the cell surface for the lipidation of HDL apolipoproteins, are not fully understood. Niemann-Pick type C (NPC) disease is most often caused by mutations in the NPC1 gene, whose protein product is believed to facilitate the egress of cholesterol and other lipids from late endosomes and lysosomes to other cellular compartments. This report reviews current knowledge regarding the role of ABCA1 in vesicular lipid transport mechanisms required for HDL particle formation, and the relationship between ABCA1 and NPC1 in this process.
