CATEGORY

transport carrier

SUBCELLULAR LOCALIZATION	plasma membrane

basic FUNCTION	Na+ (and Cl-) dependent plasma membrane, neurotransmitter transporter
	may have a role in regulation of GABAergic transmission in the brain through the reuptake of GABA into presynaptic
	terminals, as well as in osmotic regulation
	plays its main role in the liver, thereby complementing other betaine-transporting carrier proteins (SLC6A20) that are predominantly expressed in the small intestine or kidney rather than the liver

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

INTERACTION

DNA

RNA

small molecule

protein	AMPK is a powerful regulator of the organic osmolyte transporters SLC5A3 and SLC6A12 and thus interacts with cell volume regulation
	JAK2 is a novel regulator of the GABA transporter SLC6A12 (the kinase up-regulates the carrier presumably by enhancing the insertion of carrier protein into the cell membrane)

cell & other

REGULATION

activated by	tonicity responsive enhancers (TONE1-TONE2),located in the 5'flanking region of the gene
	JAK2, that up-regulates the GABA transporter BGT1 (SLC6A12)

inhibited by

can be inhibited acutely by extracellular Ca(2+) through a mechanism involving SLC6A12 internalization, and protein kinase C may play a role

ANIMAL & CELL MODELS

Bgt1-deficient and wild-type mice appeared to tolerate the salt treatment equally well, possibly because betaine is one of several osmolytes
