Phyh Gene Summary [Rat]
Enables phytanoyl-CoA dioxygenase activity. Involved in 2-oxobutyrate catabolic process and fatty acid alpha-oxidation. Located in peroxisome. Biomarker of metabolic dysfunction-associated steatotic liver disease. Human ortholog(s) of this gene implicated in Refsum disease; Zellweger syndrome; orofacial cleft; and peroxisomal disease. Orthologous to human PHYH (phytanoyl-CoA 2-hydroxylase). [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 Phyh often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
