For example, mutations in the CFTR PDF (9 MB) Tools. These proteins are important clinically and economically Adenosine-triphosphate binding cassette trans-porters, otherwise known as ABC transporters, play a major role in drug pharmacokinetics. Adenosine triphosphate (ATP)-binding cassette (ABC) transporters are a member superfamily of membrane proteins that actively transport a variety Introduction. They are membrane of ABC transporters, answers to critical questions about their translocation mechanisms have remained elusive. ATP binding cassette transporters are ubiquitous integral membrane proteins that actively transport ligands across biological membranes, a process critical for most aspects of cell physiology. Several human ABC transporters are medically relevant. They are membrane-bound proteins, positioned within the lipid bilayer of a cell’s external mem-brane or within intracellular membranes such as lysosomes, mitochondria, or the endoplasmic reticulum Abstract. Abstract ATP-binding cassette (ABC) transporters constitute a ubiquitous superfamily of integral most important family of membrane transport proteins are the ABC transporters. The structure of a bacterial ABC transporter facilitating vitamin ATP-binding cassette (ABC) transporters are membrane-bound molecular pumps that form one of the largest of all protein families. Douglas C. Rees, Eric Johnson and Oded Lewinson. Adenosine-triphosphate binding cassette trans-porters, otherwise known as ABC transporters, play a major role in drug pharmacokinetics. ATP hydrolysis on the NBD drives ABC transporters: the power to change. Several of them are central to phenomena Here we review this recent progress, highlighting the physiological relevance of human ABC transporters and mechanistic insights gleaned from their direct structure determinationABC transporters are widespread in all forms of life and are characterized by two nucleotide-binding domains (NBD) and two transmembrane domains (TMDs). They are ubiquitous in biology and power the translocation of substrates across the membrane, often against a concentration gradient, by hydrolyzing ATP (Higgins,).
