Characterization of three novel members of the Arabidopsis thaliana equilibrative nucleoside transporter (ENT) family.
Research on metabolism of nucleotides and their derivatives has gained increasing interest in the recent past. This includes de novo synthesis, analysis of salvage pathways, breakdown and transport of nucleotides, nucleosides and nucleobases. To perform a further step towards the analysis of nucleoside transport in Arabidopsis, we incubated leaf discs with various radioactively labelled nucleos...
متن کاملMalaria parasite type 4 equilibrative nucleoside transporters (ENT4) are purine transporters with distinct substrate specificity.
Malaria, caused by Plasmodia parasites, affects hundreds of millions of people. As purine auxotrophs, Plasmodia use transporters to import host purines for subsequent metabolism by the purine salvage pathway. Thus purine transporters are attractive drug targets. All sequenced Plasmodia genomes encode four ENTs (equilibrative nucleoside transporters). During the pathogenic intraerythrocytic stag...
متن کاملGenomic analysis of nucleoside transporters in Diptera and functional characterization of DmENT2, a Drosophila equilibrative nucleoside transporter.
The recent completion of genome sequencing projects in a number of eukaryotes allows comparative analysis of orthologs, which can aid in identifying evolutionary constraints on protein structure and function. Nucleoside transporters (NTs) are present in a diverse array of organisms and previous studies have suggested that there is low protein sequence similarity but conserved structure in inver...
متن کاملThe Role of Flexible Loops in Folding, Trafficking and Activity of Equilibrative Nucleoside Transporters
Equilibrative nucleoside transporters (ENTs) are integral membrane proteins, which reside in plasma membranes of all eukaryotic cells and mediate thermodynamically downhill transport of nucleosides. This process is essential for nucleoside recycling, and also plays a key role in terminating adenosine-mediated cellular signaling. Furthermore, ENTs mediate the uptake of many drugs, including anti...
متن کاملTissue distribution of concentrative and equilibrative nucleoside transporters in male and female rats and mice.
Concentrative nucleoside transporters (Cnts) and equilibrative nucleoside transporters (Ents) have essential physiological functions and are important in disposition of anticancer and antiviral nucleoside analogs. Information on tissue distribution of Cnts and Ents in rodents is sparse. Thus, the present study aimed to determine the distribution of Cnt1-3 and Ent1-3 transcripts in 19 tissues of...
