Claim: Equilibrative nucleoside transporter 1, a member of the equilibrative nucleoside transporter family encoded by the SLC29A1 gene, encodes a transmembrane glycoprotein that localizes to the plasma and mitochondrial membranes.
Evidence: This gene is a member of the equilibrative nucleoside transporter family. Equilibrative nucleoside transporter 1 (ENT1) is a protein that in humans is encoded by the SLC29A1 gene. The gene encodes a transmembrane glycoprotein that localizes to the plasma and mitochondrial membranes and mediates the cellular uptake of nucleosides from the surrounding medium.
