Mitochondrial uptake of the three branched-chain amino acids leucine (Leu), isoleucine (Ile), and valine (Val) is mediated by solute carrier family 25 member 44 (SLC25A44), localized in the inner mitochondrial membrane. This human reaction is inferred from studies of the homologous mouse protein, Slc25a44 (Yoneshiro et al. 2019).
