...Jennifer M. Evans; Jonathan P. Day; Pablo Cabrero; Julian A. T. Dow; Shireen-Anne Davies SUMMARY Guanosine 3′-5′ cyclic monophosphate (cGMP) and adenosine 3′-5′ cyclic monophosphate (cAMP) are important regulators of cell and tissue function. However, cGMP and cAMP transport have received...

... homologous to the Smf1 protein from Saccharomyces cerevisiae , which we have recently demonstrated to function as a Mn 2+ /Zn 2+ transporter. We proposed that the Drosophila and mammalian proteins, like the yeast SMF1 gene product, are metal-ion transporters. To test this hypothesis, malvolio mutant flies...

...J. Küppers; I. Bunse ABSTRACT The enzyme involved in outward K + transport in insect epithelia belongs to the family of V-ATPases. Evidence has been reported relating the generation of the K + gradient to a primary electrogenic proton transport via a distinct electrophoretic n H + /K + antiport...

...Michael G. Wolfersberger ABSTRACT Transporters are a diverse group of membrane proteins that facilitate the movement of water-soluble solutes through the lipid bilayer of biological membranes. The least complex transporters are the uniporters ( Kakuda and MacLeod, 1994 ). They simply facilitate...

...Halvor N. Christensen; Lorraine M. Albritton; Donald K. Kakuda; Carol L. Macleod ABSTRACT The molecular cloning of genes that encode amino acid transporters presents the scientific community with the opportunity to name their gene products using a scheme that could usefully recall the well-defined...
