From bacteria to mammals, ATP Binding Cassette (ABC) transporters are prevalent in many cells. ABC transporters import or export a broad spectrum of substrates, including lipids, polysaccharides, proteins or toxins across cellular membranes. With 48 known genes in the human genome, this family of membrane spanning transport proteins plays a significant role in human disease. The ABC transporter multidrug resistance protein 1 is responsible for the resistance of tumor cells to chemotherapy, while mutations in the ABC transporter cystic fibrosis transmembrane conductance regulator (CFTR) lead to cystic fibrosis, the most frequently occurring deadly inherited disease.
