Nos3 Gene Summary [Mouse]
Enables nitric-oxide synthase activity and scaffold protein binding activity. Involved in several processes, including heart development; negative regulation of muscle hyperplasia; and smooth muscle hyperplasia. Acts upstream of with a positive effect on positive regulation of gene expression. Acts upstream of or within several processes, including lipopolysaccharide-mediated signaling pathway; nitric oxide biosynthetic process; and regulation of metal ion transport. Located in cytoplasm and nucleus. Is expressed in several structures, including alimentary system; cardiovascular system; genitourinary system; hemolymphoid system gland; and nervous system. Used to study aortic valve disease; essential hypertension; persistent fetal circulation syndrome; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in several diseases, including artery disease (multiple); eye disease (multiple); leukemia (multiple); reproductive organ cancer (multiple); and vasculitis (multiple). Orthologous to human NOS3 (nitric oxide synthase 3). [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 Nos3 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
