01

Overview

Solute carrier family 2, facilitated glucose transporter member 12 (SLC2A12, also known as GLUT12) is a facilitative glucose transporter belonging to the class III subgroup of the SLC2A family[1][4]. It is widely expressed in human tissues, including skeletal muscle, adipose tissue, small intestine, heart, placenta, mammary tissue, and some cancers[1]. GLUT12 functions as a basal and largely insulin-independent glucose transporter, contributing to glucose uptake in various tissues, but it also serves as a sodium-independent, bidirectional urate transporter[3][5]. Its dysregulation is associated with altered metabolic states, cancer cell glucose metabolism, insulin sensitivity, and hyperuricemia or gout risk[1][3][5].

Other names
Glucose transporter type 12GLUT-12GLUT12
02

Mechanism of action

Facilitation of glucose uptake independently of insulin (basal transporter activity); Sodium-independent, bidirectional urate transport

03

Biological functions

Glucose transport across cell membranesFacilitation of glucose uptake in multiple tissuesUrate transport across membranesRegulation of glucose and urate homeostasis
04

Disease associations

Cancer (notably breast and prostate cancer)Hyperuricemia and goutPotential role in Alzheimer's disease (based on altered expression)Cardiovascular disease (suggested by association with glucose metabolism and insulin sensitivity)
05

Safety considerations

Dysregulation may contribute to cancer progression through increased glucose uptake in tumor cellsAltered activity can elevate blood urate levels, increasing risk for gout and hyperuricemiaOverexpression or loss of function could impair glucose or urate homeostasis
06

Biomarkers

Altered expression in certain cancers (e.g., breast and prostate) may serve as biomarker for malignancy or metabolic activityExpression associated with insulin sensitivity/resistance in metabolic disordersElevated expression observed in Alzheimer’s disease tissue
