The two most well known members of SGLT family are SGLT1 and SGLT2, which are members of the SLC5A gene family. In addition to SGLT1 and SGLT2, there are 10 other members in the human protein family SLC5A. [1] Of these, SLC5A4/SGLT3 (SAAT1) is a low-affinity transporter for glucose, but seems to have more of an electric function. [2]
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. [6] SGLT2 is located in the early proximal tubule, and is responsible for reabsorption of 80-90% of the glucose filtered by the kidney glomerulus. [7]
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 ...
SGLT2 inhibitor. SGLT2 inhibitors (also called gliflozins or flozins) are a class of medications that inhibit sodium-glucose transport proteins in the nephron (the functional units of the kidney), unlike SGLT1 inhibitors that perform a similar function in the intestinal mucosa. The foremost metabolic effect of this is to inhibit reabsorption of ...
Research suggests that having too much glucose in the body may increase production of beta-amyloid, which proteins that clump together to form plaques in the brain that have been linked to ...
Cotransporters are a subcategory of membrane transport proteins (transporters) that couple the favorable movement of one molecule with its concentration gradient and unfavorable movement of another molecule against its concentration gradient. They enable coupled or cotransport (secondary active transport) and include antiporters and symporters.
structure summary. Glucose. Glucose transporters are a wide group of membrane proteins that facilitate the transport of glucose across the plasma membrane, a process known as facilitated diffusion. Because glucose is a vital source of energy for all life, these transporters are present in all phyla.
Because sodium is absorbed at the same time as glucose via SGLT-2, the upregulation of SGLT-2 probably leads to development or maintenance of hypertension. In study where rats were given either ramipril or losartan, levels of SGLT-2 protein and mRNA were significantly reduced. In patients with diabetes, hypertension is a common problem so this ...
