ATP Binding Cassette Subfamily G Member 8 (ABCG8) Antibody

Background

ABCG8 is a membrane-bound transporter belonging to the ABCG subfamily and works as a heterodimer with ABCG5. Expressed mainly in the liver and intestine, it plays a critical role in regulating sterol transport, particularly in the excretion of cholesterol and plant sterols into bile. ABCG8 helps maintain sterol homeostasis and prevent excess sterol absorption. Mutations in ABCG8 are associated with sitosterolemia, leading to sterol accumulation and increased cardiovascular risk. This transporter is crucial for lipid metabolism and overall sterol balance.
