Solute carrier transporters (Glucose and amino acid transporters) (SLC transporters)

Glucose and amino acid transporters are integral membrane proteins, primarily belonging to the Solute Carrier (SLC) superfamily, that facilitate the movement of essential nutrients across cellular membranes [1]. Glucose transporters include the facilitative GLUT (SLC2) family and the sodium-dependent SGLT (SLC5) family, which are critical for maintaining systemic glucose homeostasis and are major targets in the treatment of type 2 diabetes [2, 4]. Amino acid transporters, such as the Large Neutral Amino Acid Transporter 1 (LAT1/SLC7A5) and Sodium-coupled Neutral Amino Acid Transporters (SNATs/SLC38), regulate protein synthesis, neurotransmission, and metabolic signaling [3]. These transporters are frequently dysregulated in diseases; for instance, SGLT2 is targeted to reduce renal glucose reabsorption, while LAT1 is often overexpressed in various cancers to support rapid cell proliferation [5]. Therapeutic strategies include the use of small molecule inhibitors to block nutrient uptake in cancer or metabolic disease, as well as the design of prodrugs that exploit these transporters for improved bioavailability [1, 3]. Understanding the specific expression patterns and substrate specificities of these transporters is vital for developing targeted therapies and diagnostic tools [1].
