ARSP3

ARSP3, also known as ATP-binding cassette subfamily A member 3, is a protein encoded by the ARSP3 gene in humans. This gene is part of the ATP-binding cassette (ABC) transporter superfamily, a large group of membrane proteins that utilize the energy from ATP hydrolysis to transport various molecules across cellular membranes. ARSP3 plays a role in the transport of lipids and other substances, though its precise physiological functions are still under investigation.

Research suggests that ARSP3 is involved in cellular processes related to cholesterol metabolism and lipid homeostasis. It is expressed in various tissues, with notable presence in the liver and adrenal glands. Mutations in the ARSP3 gene have been linked to certain genetic disorders, impacting lipid profiles and potentially contributing to cardiovascular issues. The protein's structure is characteristic of ABC transporters, featuring nucleotide-binding domains and transmembrane domains that facilitate its transport activity. Ongoing studies aim to further elucidate the specific substrates and mechanisms of ARSP3, as well as its implications in disease pathogenesis. Understanding its function could offer new therapeutic targets for lipid-related metabolic diseases.
