Dhodh Gene Summary [Rat]
Enables FMN binding activity; dihydroorotate dehydrogenase activity; and ubiquinone binding activity. Involved in several processes, including 'de novo' pyrimidine nucleobase biosynthetic process; lactation; and response to L-arginine. Located in mitochondrial inner membrane and neuronal cell body. Human ortholog(s) of this gene implicated in postaxial acrofacial dysostosis. Orthologous to human DHODH (dihydroorotate dehydrogenase (quinone)). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Dhodh often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
