Recent advances in the molecular biology of nucleoside transporters of mammalian cells

Cass, Carol E, Young, James D, Baldwin, Stephen A·1998·Biochemistry and Cell Biology

Abstract

Nucleosides are hydrophilic molecules and require specialized transport proteins for permeation of cell membranes. There are two types of nucleoside transport processes: equilibrative bidirectional processes driven by chemical gradients and inwardly directed concentrative processes driven by the sodium electrochemical gradient. The equilibrative nucleoside transport processes (es, ei) are found in most mammalian cell types, whereas the concentrative nucleoside transport processes (cit, cif, cib, csg, cs) are present primarily in specialized epithelia. Using a variety of cloning strategies and functional expression in oocytes of Xenopus laevis, we have isolated and characterized cDNAs encoding the rat and human nucleoside transporter proteins of the four major nucleoside transport processes of mammalian cells (es, ei, cit, cif). From the sequence relationships of these proteins with each other and with sequences in the public data bases, we have concluded that the equilibrative and concentrative nucleoside transport processes are mediated by members of two previously unrecognized groups of integral membrane proteins, which we have designated the equilibrative nucleoside transporter (ENT) and the concentrative nucleoside transporter (CNT) protein families. This review summarizes the current state of knowledge in the molecular biology of the ENT and CNT protein families, focusing on the characteristics of the four human (h) and rat (r) nucleoside transport proteins (r/hENT1, r/h…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
