Differential expression of adenine nucleotide translocator isoforms in mammalian tissues and during muscle cell differentiation.

The adenine nucleotide translocator (ANT) catalyzes the exchange of ADP and ATP across the mitochondrial internal membrane. Its three isoforms, ANT1, ANT2, and ANT3 are coded by differentially regulated nuclear genes. The patterns of expression of these genes in human, bovine, and mouse tissue are similar. ANT1 is highly expressed in heart and skeletal muscle and is induced during myoblast differentiation. It is coordinately regulated with the nuclear gene for the mitochondrial ATP synthase beta subunit, with which it shares the positive muscle cis element, the OXBOX. ANT2 is either absent or weakly expressed in all tissues. ANT3 is ubiquitously expressed in all tissues, and its transcript level is proportional to the level of oxidative metabolism. The tissue-specific expression of the ANT gene family thus provides insight into the molecular basis of the differential reliance of mammalian tissues on oxidative phosphorylation.[1]
