ABCC1, also known as Multidrug Resistance Protein 1 (MRP1), is a member of the ATP-Binding Cassette (ABC) transporter family. This protein plays a crucial role in the transport of various substrates across extra- and intracellular membranes. It is involved in the efflux of organic anions, including chemotherapeutic agents, out of cells, which can contribute to multidrug resistance in cancer therapy.
