Summaries for SLC25A15 Gene

Entrez Gene Summary for SLC25A15 Gene

  • This gene is a member of the mitochondrial carrier family. The encoded protein transports ornithine across the inner mitochondrial membrane from the cytosol to the mitochondrial matrix. The protein is an essential component of the urea cycle, and functions in ammonium detoxification and biosynthesis of the amino acid arginine. Mutations in this gene result in hyperornithinemia-hyperammonemia-homocitrullinuria (HHH) syndrome. There is a pseudogene of this locus on the Y chromosome.[provided by RefSeq, May 2009]

GeneCards Summary for SLC25A15 Gene

SLC25A15 (Solute Carrier Family 25 Member 15) is a Protein Coding gene. Diseases associated with SLC25A15 include Hyperornithinemia-Hyperammonemia-Homocitrullinemia Syndrome and Hyperammonemia. Among its related pathways are Metabolism and Regulation of activated PAK-2p34 by proteasome mediated degradation. GO annotations related to this gene include L-ornithine transmembrane transporter activity. An important paralog of this gene is SLC25A2.
