Cpt1b Gene Summary [Mouse]
Enables carnitine O-palmitoyltransferase activity. Involved in carnitine shuttle and response to blue light. Located in mitochondrion. Is active in mitochondrial intermembrane space. Is expressed in brown fat; cardiovascular system; early conceptus; and ovary. Orthologous to human CPT1B (carnitine palmitoyltransferase 1B). [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 mouse Cpt1b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
