GABA (gamma-aminobutyrate) is transported across the inner mitochondrial membrane into the mitochondrial matrix. Studies of isolated mitochondria from rat and mouse brains together showed that GABA uptake into isolated mitochondria is energy- and Na+-dependent (Berkich et al. 2007; Kuriyama et al. 1969; Passarella et al. 1984), and Michaeli et al. (2011) have characterized an Arabidopsis protein that mediates mitochondrial GABA uptake, but no mammalian mitochondrial GABA transporter has been identified.
