SLC46 family of folate transporters

Unless otherwise stated all data on this page refer to the human proteins. Gene information is provided for human (Hs), mouse (Mm) and rat (Rn).

Overview

« Hide

Based on the proptypical member of this family, PCFT, this family includes proton-driven transporters with 11 TM segments. SLC46A1 has been described to act as an intestinal proton-coupled high-affinity folic acid transporter [2], with lower affinity for heme. folic acid accumulation is independent of Na+ or K+ ion concentrations, but driven by extracellular protons with an as yet undefined stoichiometry.
