ABCC1
abcc1: A Membrane Transporter with Diverse Roles in Health and Disease
Description
ABCC1, also known as the multidrug resistance-associated protein 1 (MRP1), is a membrane transporter protein that plays a crucial role in cellular detoxification and drug resistance. It belongs to the ATP-binding cassette (ABC) superfamily of proteins, which utilize energy from ATP hydrolysis to transport various substrates across cellular membranes. ABCC1 is primarily expressed in the liver, kidneys, and blood-brain barrier, where it transports a wide range of molecules, including drugs, metabolites, and toxins.
Associated Diseases
Dysregulation of ABCC1 activity has been linked to several diseases, including:
- Cancer: ABCC1 contributes to drug resistance in cancer cells by actively effluxing chemotherapeutic agents. Overexpression of ABCC1 has been associated with poor prognosis in various malignancies.
- Liver disease: Mutations in the ABCC1 gene can lead to progressive familial intrahepatic cholestasis (PFIC), a rare genetic disorder characterized by impaired bile flow and liver damage.
- Kidney disease: ABCC1 plays a role in the excretion of toxins and metabolic waste products from the kidneys. Reduced expression or activity of ABCC1 can contribute to kidney dysfunction and disease.
- Neurological disorders: ABCC1 transports various compounds that are essential for brain function. Alterations in ABCC1 activity have been implicated in the pathogenesis of Alzheimer's disease and other neurodegenerative disorders.
Did you Know ?
ABCC1 is responsible for the efflux of approximately 40% of clinically used drugs, highlighting its significant role in drug resistance and pharmacokinetics.
