The sodium glucose cotransporter 1 is classified as an integral membrane protein that is made up of 14 alpha-helices constructed from the folding of amino acid residues with both the N and C-terminal residing upon the extracellular side of the plasma membrane. Glucose transporters are integral membrane proteins that mediate the transport of glucose and structurally related substances across cellular membranes. Two families of glucose transporter have been identified: the facilitated diffusion glucose transporter family GLUT family , also known as uniporters , and the sodium-dependent glucose transporter family SGLT family , also known as cotransporters or symporters. The sodium glucose cotransporter is original arranged with an outward-facing conformation with open receptors in preparation for 2 sodium ions and glucose to simultaneously bind. Co-transport proteins of mammalian cell membranes had eluded efforts of purification with classical biochemical methods until the late s. The rabbit form of SGLT1 was the first mammalian co-transport protein ever to be cloned and sequenced, and this was reported in

Glucose transport across the cell membrane is mediated by two types of transporters: facilitative glucose transporters gene name: solute carrier 2A and sodium—glucose cotransporters SGLTs; gene name: solute carrier 5A. Each transporter has its own substrate specificity, distribution, and regulatory mechanisms. Sodium—glucose cotransporter 1 and sodium—glucose cotransporter 2 have attracted much attention as therapeutic targets for various diseases. In mammals, glucose movement into and out of cells is achieved by glucose transporters GLUTs on the cell membrane. GLUTs are divided into two structurally and functionally distinct types: i GLUTs, which operate by facilitated diffusion 1 , 2 ; and ii sodium—glucose cotransporters SGLTs , which actively transport glucose against the concentration gradient by coupling with sodium 3 , 4. GLUTs are located in all body cells to facilitate transport of glucose into the cells, and the concentrations of glucose into and out of the cells become equal with GLUTs operation 1. In the SGLTs, which comprise a family of at least six different isoforms in humans, glucose and sodium are simultaneously cotransported into the cells using the sodium concentration gradient 5. In the intestinal epithelium, glucose influx into the epithelial cells is catalyzed by SGLT1 located in the apical membrane, and the glucose flows into the circulation through GLUT2 located in the basolateral membrane 5 , 7. Recently, SGLT2 inhibitors have been developed, based on a new concept of antidiabetic action by inhibiting renal glucose reabsorption and increasing glucose excretion into urine. Furthermore, SGLT1 is responsible for glucose absorption in the small intestine and for reabsorption of the part of the filtered glucose load in the kidney 10 , and might be an attractive target for the maintenance of good glycemic control and improvement of renal dysfunction 7 , The facilitative glucose transporters, GLUTs, use the diffusion gradient of glucose or other sugars across cell membranes, each with unique substrate specificities, kinetic profile and expression profile in tissues 4.

SGLT2 is a member of the sodium glucose cotransporter family , which are sodium-dependent glucose transport proteins. SGLT2 is the major cotransporter involved in glucose reabsorption in the kidney. SGLT2 inhibitors are also called gliflozins or flozins. They lead to a reduction in blood glucose levels, and therefore have potential use in the treatment of type 2 diabetes. Gliflozins enhance glycemic control as well as reduce body weight and systolic and diastolic blood pressure. Mutations in this gene are also associated with renal glycosuria.
