Abstract
The mitochondrial ADP/ATP carriers (AACs) catalyze the exchange of cytosolic ADP for matrix ATP. We have identified and characterized a novel member of the AAC subfamily of mitochondrial metabolite transport proteins, termed AAC4. The AAC4 gene maps to human chromosome 4q28.1, and its product AAC4 is 66-68% identical to human AAC 1-3 and is localized to mitochondria. AAC4 transcripts are exclusively present in liver, testis and brain unlike those of AAC 1-3. Consistent with its belonging to the AAC subfamily, upon heterologous expression and reconstitution into liposomes AAC4 exchanges ADP for ATP by an electrogenic antiport mechanism with high specificity and high sensitivity to carboxyatractyloside and bongkrekic acid.Entities:
