Probable retinal pigment epithelium (RPE)-specific proton-coupled L-lactate transporter (By similarity). May facilitate transport of lactate and H(+) out of the retina and could therefore play a role in pH and ion homeostasis of the outer retina (By similarity).
Subcellular locations: Basolateral cell membrane
Basolateral sorting signals (BLSS) in C-terminal cytoplasmic tail ensure its basolateral expression . Colocalizes with BSG in basolateral cell membrane of the retinal pigment epithelium (By similarity).
