Summary: Predicted to enable several functions, including identical protein binding activity; ornithine carbamoyltransferase activity; and phosphate ion binding activity. Predicted to be involved in several processes, including ammonium homeostasis; non-proteinogenic amino acid metabolic process; and urea cycle. Located in mitochondrial inner membrane. Is expressed in alimentary system; intestine; intrahepatic bile duct epithelium; liver; and small intestine. Used to study ornithine carbamoyltransferase deficiency. Human ortholog(s) of this gene implicated in ornithine carbamoyltransferase deficiency. Orthologous to human OTC (ornithine transcarbamylase). [provided by Alliance of Genome Resources, Dec 2024]

An Exon-Specific Small Nuclear U1 RNA (ExSpeU1) Improves Hepatic OTC Expression in a Splicing-Defective spf/ash Mouse Model of Ornithine Transcarbamylase Deficiency.
Title: An Exon-Specific Small Nuclear U1 RNA (ExSpeU1) Improves Hepatic OTC Expression in a Splicing-Defective spf/ash Mouse Model of Ornithine Transcarbamylase Deficiency.
Gene correction in adult OTC-deficient mice was lower and accompanied by larger deletions that ablated residual expression from the endogenous OTC gene, leading to diminished protein tolerance and lethal hyperammonemia on a chow diet
Title: A dual AAV system enables the Cas9-mediated correction of a metabolic liver disease in newborn mice.
The corresponding OTC tissue enzyme activities were between 3-6% of normal control in mouse and human liver. The use of the cryptic splice sites was reproduced in minigenes carrying murine or human mutant sequences
Title: Functional characterization of the spf/ash splicing variation in OTC deficiency of mice and man.
Serum OCT seemed to reflect tumor necrosis factor-alpha-mediated hepatic damage in diabetic obese mice and could be useful in the application for non-alcoholic fatty liver disease with features of metabolic syndrome, such as obesity and diabetes.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
