CC -!- FUNCTION: Probable retinal pigment epithelium (RPE)-specific proton- CC coupled L-lactate transporter (Probable). May facilitate transport of CC lactate and H(+) out of the retina and could therefore play a role in CC pH and ion homeostasis of the outer retina (By similarity). CC {ECO:0000250|UniProtKB:O35308, ECO:0000305|PubMed:10924129, CC ECO:0000305|PubMed:9168967}. CC -!- CATALYTIC ACTIVITY: CC Reaction=(S)-lactate(in) + H(+)(in) = (S)-lactate(out) + H(+)(out); CC Xref=Rhea:RHEA:29415, ChEBI:CHEBI:15378, ChEBI:CHEBI:16651; CC Evidence={ECO:0000305|PubMed:10924129}; CC -!- BIOPHYSICOCHEMICAL PROPERTIES: CC Kinetic parameters: CC KM=6 mM for L-lactate {ECO:0000269|PubMed:10924129}; CC -!- SUBCELLULAR LOCATION: Basolateral cell membrane CC {ECO:0000269|PubMed:10924129, ECO:0000269|PubMed:7628551}; Multi-pass CC membrane protein {ECO:0000255}. Note=Basolateral sorting signals (BLSS) CC in C-terminal cytoplasmic tail ensure its basolateral expression (By CC similarity). Colocalizes with BSG in basolateral cell membrane of the CC retinal pigment epithelium (By similarity). CC {ECO:0000250|UniProtKB:O35308, ECO:0000250|UniProtKB:O95907}. CC -!- TISSUE SPECIFICITY: Retinal pigment epithelium. CC {ECO:0000269|PubMed:7628551, ECO:0000269|PubMed:9168967}. CC -!- DEVELOPMENTAL STAGE: First detected at embryonic day 5 (5 dpc) in both CC apical and basolateral membranes. By 14 dpc the distribution is CC restricted to the basolateral surface of retinal pigment epithelium. CC Restricted to the basolateral membrane in adult. CC {ECO:0000269|PubMed:7628551}. CC -!- DOMAIN: The two basolateral sorting signals (BSS) are required to CC direct SLC16A8 to the basolateral membrane. CC {ECO:0000250|UniProtKB:O95907}. CC -!- SIMILARITY: Belongs to the major facilitator superfamily. CC Monocarboxylate porter (TC 2.A.1.13) family. {ECO:0000305}.
