SLC23 family of ascorbic acid transporters in GtoPdb v.2023.3

Abstract

Predicted to be 12 TM segment proteins, members of this family transport the reduced form of ascorbic acid (while the oxidized form may be handled by members of the SLC2 family (GLUT1/SLC2A1, GLUT3/SLC2A3 and GLUT4/SLC2A4). phloretin is considered a non-selective inhibitor of these transporters, with an affinity in the micromolar range [1].
