Dual regulation of SLC25A39 by AFG3L2 and iron controls mitochondrial glutathione homeostasis Maintenance of small molecule redox homeostasis in mitochondria Jacobs 2023 FEBS Letters Wiley Online Library 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 Combinatorial GxGxE CRISPR screen identifies SLC25A39 in mitochondrial glutathione transport linking iron homeostasis to OXPHOS Nature Communications
