ADP/ATP translocase 4 (adenine nucleotide translocator 4, ANT 4, ADP,ATP carrier protein 4, sperm flagellar energy carrier protein, solute carrier family 25 member 31, SLC25A31, AAC4, ANT4, SFEC)

Function

• catalyzes the exchange of ADP & ATP across the mitochondrial inner membrane
• may serve to mediate energy generating & energy consuming processes in the distal flagellum, possibly as a nucleotide shuttle between flagellar glycolysis, protein phosphorylation & mechanisms of motility

Structure

• belongs to the mitochondrial carrier family
• contains 3 Solcar repeats

Compartment

• mitochondrial inner membrane
• in sperm flagellum, located in the fibrous sheath, a non-mitochondrial region

Expression

expressed in brain, liver, sperm & testis

More general terms

• solute carrier family 25 (SLC25, SLC25A)
• mitochondrial membrane protein
