Abstract excerpt
OTC encodes ornithine carbamoyltransferase, mitochondrial matrix enzyme involved in the synthesis of urea. The tissue-specific expression of OTC in the liver and intestine is dependent on the interaction of OTC promoter with an upstream enhancer. HNF-4 and C/EBPβ are crucial for this interaction in the rat and mouse. In the present study we focused on characterization of elements involved in the regulation of OTC...
