title: Amino acid transport in the renal proximal tubule.
abstract: In the kidney the proximal tubule is responsible for the uptake of amino acids. This occurs via a variety of functionally and structurally different amino acid transporters located in the luminal and basolateral membrane. Some of these transporters show an ion-dependence (e.g. Na+, Cl- and K+) or use an H+-gradient to drive transport. Only a few amino acid transporters have been cloned or functionally characterized in detail so far and their structure is known, while little is known about a majority of amino acid transporters. Only few attempts have been untertaken looking at the regulation of amino acid transport. We summarized more recent information on amino acid transport in the renal proximal tubule emphasizing functional and regulatory aspects.
