Cpt2 Gene Summary [Rat]
Enables carnitine O-palmitoyltransferase activity. Involved in fatty acid beta-oxidation and response to fatty acid. Predicted to be located in nucleolus and nucleoplasm. Predicted to be active in mitochondrial matrix. Human ortholog(s) of this gene implicated in brain disease; lipid metabolism disorder; and muscular disease. Orthologous to human CPT2 (carnitine palmitoyltransferase 2). [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 Cpt2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
