Proton-linked monocarboxylate transporter. May catalyze the transport of monocarboxylates across the plasma membrane (Probable). Probably involved in hepatic lipid metabolism: overexpression results in an increase of triacylglycerol(TAG) levels, small increases in intracellular diacylglycerols and decreases in lysophosphatidylcholine, cholesterol ester and sphingomyelin lipids.
