Nos2 Gene Summary [Rat]
Enables several functions, including Hsp90 protein binding activity; beta-catenin binding activity; and enzyme binding activity. Involved in several processes, including cellular response to cytokine stimulus; response to bacterium; and response to hexose. Acts upstream of or within cellular response to cytokine stimulus. Located in several cellular components, including extracellular space; perinuclear region of cytoplasm; and peroxisome. Used to study several diseases, including Alzheimer's disease; diabetic angiopathy; pleurisy; renal hypertension; and toxic shock syndrome. Biomarker of several diseases, including acute necrotizing pancreatitis; artery disease (multiple); inflammatory bowel disease (multiple); liver disease (multiple); and lung disease (multiple). Human ortholog(s) of this gene implicated in several diseases, including dementia (multiple); hypertension (multiple); malaria; pulmonary tuberculosis; and type 2 diabetes mellitus. Orthologous to human NOS2 (nitric oxide synthase 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 Nos2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
