Collectrin and ACE2 in renal and intestinal amino acid transport


Singer, D; Camargo, S M R (2011). Collectrin and ACE2 in renal and intestinal amino acid transport. Channels, 5(5):410-423.

Abstract

Neutral amino acid transporters of the SLC6 family are expressed at the apical membrane of kidney and/or small intestine, where they (re-)absorb amino acids into the body. In this review we present the results concerning the dependence of their apical expression with their association to partner proteins. We will in particular focus on the situation of B0AT1 and B0AT3, that associate with members of the renin-angiotensin system (RAS), namely Tmem27 and angiotensin-converting enzyme 2 (ACE2), in a tissue specific manner. The role of this association in relation to the formation of a functional unit related to Na+ or amino acid transport will be assessed. We will conclude with some remarks concerning the relevance of this association to Hartnup disorder, where some mutations have been shown to differentially interact with the partner proteins.

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.
