Recombinant human SLC2A2 protein, also known as glucose transporter 2 (GLUT2), is a facilitative transporter protein critical for glucose homeostasis. Encoded by the SLC2A2 gene, it belongs to the solute carrier 2 family and facilitates bidirectional glucose transport across cell membranes. Structurally, it contains 12 transmembrane domains with intracellular N- and C-termini. GLUT2 is predominantly expressed in metabolically active tissues, including the liver, pancreatic β-cells, kidneys, and small intestine, where it enables cellular uptake or release of glucose, depending on concentration gradients.
Recombinant SLC2A2 is produced using expression systems like *E. coli* or mammalian cells to study its function *in vitro*. Its low-affinity, high-capacity transport properties make it pivotal for sensing blood glucose levels in pancreatic β-cells and regulating hepatic glucose uptake/storage. Dysregulation of SLC2A2 is linked to diabetes, as impaired function disrupts insulin secretion and glucose tolerance. Additionally, mutations in SLC2A2 cause Fanconi-Bickel syndrome, a rare glycogen storage disorder.
Recombinant GLUT2 aids in drug development targeting glucose metabolism disorders and provides insights into transporter kinetics or ligand interactions. Its role in fructose and galactose transport also expands its relevance in dietary studies. Research continues to explore therapeutic strategies modulating SLC2A2 activity to manage metabolic diseases.
