GLUT1

GLUT1 (SLC2A1) provides basal glucose uptake and supports cellular glucose transport across physiological and pathological contexts[1]. Mechanistically, GLUT1 belongs to the sugar porter family, where glucose transport depends on conserved substrate coordination and conformational regulation[2]. In disease models, impaired GLUT1 function causes Glut1 deficiency syndrome, a brain energy failure syndrome driven by reduced glucose transport across brain tissue barriers[3][4]. Compared with GLUT3, GLUT1 shares a conserved substrate-binding site but differs in transport affinity, making isoform distinction essential for transporter-specific experimental design[2]. GLUT1 and GLUT3 also transport dehydroascorbic acid, whereas GLUT2, GLUT5, and SGLT1 do not transport DHA in the tested oocyte system[5]. For experimental applications, WZB117 inhibits GLUT1-mediated sugar transport and downregulates glycolysis, supporting its use in glucose uptake and cancer metabolism studies[6][7].
