SLC16A1

The protein encoded by this gene is a proton-linked monocarboxylate transporter that catalyzes the movement of many monocarboxylates, such as lactate and pyruvate, across the plasma membrane. Mutations in this gene are associated with erythrocyte lactate transporter defect. Alternatively spliced transcript variants have been found for this gene.

SOLUTE CARRIER FAMILY 16 MEMBER 1

Proton-coupled monocarboxylate transporter. Catalyzes the rapid transport across the plasma membrane of many monocarboxylates such as lactate, pyruvate, branched-chain oxo acids derived from leucine, valine and isoleucine, and the ketone bodies acetoacetate, beta-hydroxybutyrate and acetate. Depending on the tissue and on cicumstances, mediates the import or export of lactic acid and ketone bodies. Required for normal nutrient assimilation, increase of white adipose tissue and body weight gain when on a high-fat diet. Plays a role in cellular responses to a high-fat diet by modulating the cellular levels of lactate and pyruvate, small molecules that contribute to the regulation of central metabolic pathways and insulin secretion, with concomitant effects on plasma insulin levels and blood glucose homeostasis.

Cell membrane

Symptomatic deficiency in lactate transport (SDLT):
Deficiency of lactate transporter may result in an acidic intracellular environment created by muscle activity with consequent degeneration of muscle and release of myoglobin and creatine kinase. This defect might compromise extreme performance in otherwise healthy individuals.
Familial hyperinsulinemic hypoglycemia 7 (HHF7):
Dominantly inherited hypoglycemic disorder characterized by inappropriate insulin secretion during anaerobic exercise or on pyruvate load.
Monocarboxylate transporter 1 deficiency (MCT1D):
A metabolic disorder characterized by recurrent ketoacidosis, a pathologic state due to ketone formation exceeding ketone utilization. The clinical consequences of ketoacidosis are vomiting, osmotic diuresis, dehydration, and Kussmaul breathing. The condition may progress to decreased consciousness and, ultimately, death.
