SLC25A2 (Solute Carrier Family 25 Member 2): SLC25A2 is a gene that encodes a mitochondrial transport protein responsible for moving ornithine across the mitochondrial membrane. This transport is crucial for the urea cycle and amino acid metabolism. Dysfunction in SLC25A2 can lead to metabolic disorders, highlighting its important role in metabolic pathways and its potential as a therapeutic target for related diseases.
