Eye Res. 67:417-424(1998). CC -!- FUNCTION: Proton-linked monocarboxylate transporter. Catalyzes the CC rapid transport across the plasma membrane of many monocarboxylates CC such as lactate, pyruvate, branched-chain oxo acids derived from CC leucine, valine and isoleucine, and the ketone bodies acetoacetate, CC beta-hydroxybutyrate and acetate (By similarity). {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein. CC -!- TISSUE SPECIFICITY: Retinal pigment epithelium. CC -!- DEVELOPMENTAL STAGE: First detected at embryonic day 5 (E5) in both CC apical and basolateral membranes. By E14 the distribution is restricted CC to the basolateral surface of retinal pigment epithelium. Restricted to CC the basolateral membrane in adult. CC -!- SIMILARITY: Belongs to the major facilitator superfamily. CC Monocarboxylate porter (TC 2.A.1.13) family. {ECO:0000305}.
