Mitochondrial membrane carrier protein that mediates the import of NAD(+) into mitochondria . Compared to SLC25A51, SLC25A52-mediated transport is not essential for the import of NAD(+) in mitochondria . The transport mechanism, uniport or antiport, its electrogenicity and substrate selectivity, remain to be elucidated.
