General Information and Variability Data of DT
DT ID	DTD0100
Gene Name	SLC16A1
Protein Name	Monocarboxylate transporter 1
Synonyms	HHF7; MCT; MCT 1; MCT1; MCT1D; SLC16A1; Solute carrier family 16 member 1
Gene ID	6566
UniProt ID	P53985
TCDB ID	2.A.1.13.1
DT Family	Major Facilitator Superfamily (MFS)
	Monocarboxylate Transporter (MCT) Family
Tissue Specificity	Detected in heart and in blood lymphocytes andmonocytes (at protein level). Widely expressed.
Function	This proton-coupled transporter can mediates 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.
