ATP Binding Cassette Subfamily G Member 5 (ABCG5) Antibody

Background

ABCG5 is an integral membrane protein and part of the ATP-binding cassette (ABC) transporter family, specifically subfamily G. Expressed primarily in the liver and intestines, ABCG5 works in tandem with ABCG8 to regulate dietary sterol absorption and biliary sterol excretion. It plays a vital role in maintaining cholesterol and plant sterol homeostasis. Mutations in ABCG5 are linked to sitosterolemia, a rare autosomal recessive disorder characterized by hyperabsorption of plant sterols and cholesterol. Its function is essential for reducing sterol accumulation and preventing cardiovascular diseases.
