Protein

Mitochondrial ornithine transporter 1

Gene

SLC25A15

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Ornithine-citrulline antiporter. Connects the cytosolic and the intramitochondrial reactions of the urea cycle by exchanging cytosolic ornithine with matrix citrulline (PubMed:12807890). The stoichiometry is close to 1:1 (By similarity).By similarity1 Publication

Involvement in diseasei

Hyperornithinemia-hyperammonemia-homocitrullinuria syndrome (HHH syndrome)7 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAutosomal recessive disorder resulting in various neurologic symptoms, including mental retardation, spastic paraparesis with pyramidal signs, cerebellar ataxia, and episodic disturbance of consciousness or coma caused by hyperammonemia. It causes a functional impairment of the urea cycle.
