The sodium/glucose cotransporter 2 (SGLT2) is a protein that in humans is encoded by the SLC5A2 (solute carrier family 5 (sodium/glucose cotransporter)) gene.[1]

Function

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.[2]

SGLT2 inhibitors for diabetes

Main article: Gliflozin

SGLT2 inhibitors are called gliflozins and lead to a reduction in blood glucose levels. Therefore, SGLT2 inhibitors have potential use in the treatment of type II diabetes. As studied on canagliflozin, a member of this class of drugs, gliflozins enhance glycemic control as well as reduce body weight and systolic and diastolic blood pressure.[3] The gliflozins canagliflozin, dapagliflozin, and empagliflozin may lead to ketoacidosis.[4] Other side effects of gliflozins include increased risk of (generally mild) urinary tract infections, candidal vulvovaginitis and hypoglycemia.[5]

Clinical significance

Mutations in this gene are also associated with renal glucosuria.[6]

Model organisms

Model organisms have been used in the study of SLC5A2 function. A conditional knockout mouse line, called Slc5a2tm1a(KOMP)Wtsi[12][13] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[14][15][16]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[10][17] Twenty two tests were carried out on homozygous mutant mice and one significant abnormality was observed: males displayed increased drinking behaviour.[10]
