SLC25A48 controls mitochondrial choline import and metabolism Choline metabolism depends on its mitochondrial import, but the mechanism remains unknown. SLC25A48 is a previously uncharacterized mitochondrial inner membrane carrier protein. The SLC25A39 is necessary for mitochondrial glutathione import in mammalian cells Nature Scientists discover how mitochondria import antioxidants SLC25A39 identified as a key regulator of hepatocellular carcinoma progression through the mitochondrial ROScytochrome ccaspase signaling axis Cellular & Molecular Biology Letters Springer Nature Link
