Abstract

The availability of cloned transport molecules achieved by efforts in expression cloning has allowed their electrophysiological analysis in the Xenopus oocyte expression system. We describe the electrogenic uptake of various substrates by their corresponding transport molecules originally expressed in brush border membranes of proximal tubules. The functional properties of the following transport molecules are discussed: the sodium-coupled glucose transporter, the sodium-coupled phosphate transporter, the sodium-coupled sulfate transporter and the sodium-independent transporter of neutral and dibasic amino acids. Additionally, functional consequences of naturally occurring disease-causing mutations in some of these transport molecules are described.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
