SLC16A1. also known as monocarboxylate transporter 1 (MCT1), is a member of the solute carrier (SLC) superfamily responsible for the proton-coupled transport of monocarboxylates such as lactate, pyruvate, and ketone bodies across cell membranes. It plays a critical role in cellular metabolism, particularly in tissues with high energy demands or under hypoxic conditions. By shuttling lactate between glycolytic and oxidative cells (e.g., the "lactate shuttle" in muscle and brain), MCT1 helps maintain metabolic flexibility and pH balance. Its expression is upregulated in cancer cells to support the Warburg effect, where tumors rely on glycolysis even under oxygen-rich conditions, producing excess lactate that requires export.
Recombinant SLC16A1 protein is engineered for in vitro studies to elucidate its structure-function relationships, substrate specificity, and regulatory mechanisms. Produced using heterologous expression systems like mammalian cells or yeast, the recombinant protein retains key features such as 12 transmembrane domains and binding sites for substrates/inhibitors. Researchers use it to investigate interactions with partner proteins like CD147/Basigin, essential for MCT1 membrane localization, or to screen therapeutic agents targeting diseases linked to MCT1 dysfunction. For example, MCT1 inhibitors (e.g., AZD3965) are being explored in cancer therapy to disrupt lactate efflux and induce metabolic stress in tumors.
Additionally, recombinant SLC16A1 aids in studying metabolic disorders, neurodegenerative diseases, and drug absorption, as MCT1 mediates intestinal uptake of pharmaceutical monocarboxylates. Its role in transporting β-hydroxybutyrate also links it to ketogenic diet effects and brain energy homeostasis. Challenges include preserving native conformation during purification due to its transmembrane nature, but advances in cryo-EM and stabilizers have improved structural insights. Overall, recombinant SLC16A1 serves as a vital tool for decoding metabolic reprogramming in diseases and developing precision therapies.
