SLC25A4 is a gene that encodes a protein known as the adenine nucleotide translocator (ANT). This protein is primarily located in the inner mitochondrial membrane and plays a crucial role in transporting ATP, the energy currency of the cell, into the mitochondria while exporting ADP. This process is essential for maintaining cellular energy levels. Mutations in the SLC25A4 gene can lead to various health issues, including mitochondrial myopathy, a condition that affects muscle function and energy production. Understanding the function of this gene is important for developing potential treatments for related disorders.
