Nnmt Gene Summary [Mouse]
Enables nicotinamide N-methyltransferase activity. Involved in NAD catabolic process; nicotinamide metabolic process; and positive regulation of metabolic process. Acts upstream of or within methylation. Is active in cytosol. Is expressed in brown fat. Human ortholog(s) of this gene implicated in abdominal aortic aneurysm. Orthologous to human NNMT (nicotinamide N-methyltransferase). [provided by Alliance of Genome Resources, Apr 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 Nnmt often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
