FunctionCatalyzes the exchange of ADP and ATP across the mitochondrial inner membrane. May serve to mediate energy generating and energy consuming processes in the distal flagellum, possibly as a nucleotide shuttle between flagellar glycolysis, protein phosphorylation and mechanisms of motility.
Tissue specificityExpressed in brain, liver, sperm and testis.
Sequence similaritiesBelongs to the mitochondrial carrier family. Contains 3 Solcar repeats.
Cellular localizationMitochondrion inner membrane. Cell projection > cilium > flagellum. In sperm flagellum this protein is located in the fibrous sheath, a non-mitochondrial region.
