CC -!- FUNCTION: Mediates the electroneutral exchange of acylcarnitines (O-
CC acyl-(R)-carnitine or L-acylcarnitine) of different acyl chain lengths
CC (ranging from O-acetyl-(R)-carnitine to long-chain O-acyl-(R)-
CC carnitines) with free carnitine ((R)-carnitine or L-carnitine) across
CC the mitochondrial inner membrane, via a ping-pong mechanism. Key player
CC in the mitochondrial oxidation pathway, it translocates the fatty acids
CC in the form of acylcarnitines into the mitochondrial matrix, where the
CC carnitine palmitoyltransferase 2 (CPT-2) activates them to undergo
CC fatty acid beta-oxidation. Catalyzes the unidirectional transport
CC (uniport) of carnitine at lower rates than the antiport (exchange).
CC {ECO:0000250|UniProtKB:O43772}.
