Summaries for SLC25A2 Gene

Entrez Gene Summary for SLC25A2 Gene

  • This intronless gene encodes a protein that localizes to the mitochondrial inner membrane and likely functions as a transporter of small molecules such as ornithine. This gene is located between the protocadherin beta and gamma gene clusters on chromosome 5. [provided by RefSeq, Dec 2014]

GeneCards Summary for SLC25A2 Gene

SLC25A2 (Solute Carrier Family 25 Member 2) is a Protein Coding gene. Diseases associated with SLC25A2 include Hyperornithinemia-Hyperammonemia-Homocitrullinemia Syndrome. Among its related pathways are CDK-mediated phosphorylation and removal of Cdc6 and Viral mRNA Translation. An important paralog of this gene is SLC25A15.
