The function of ENSG00000100156 (SLC16A8, solute carrier family 16 member 8) is as follows. 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). .
