Enables nitric-oxide synthase activity. Involved in several processes, including nitric oxide biosynthetic process; positive regulation of adenylate cyclase-activating G protein-coupled receptor signaling pathway; and positive regulation of the force of heart contraction. Acts upstream of or within
several processes, including peptidyl-cysteine S-nitrosylation; positive regulation of transcription by RNA polymerase II; and regulation of metal ion transport. Located in several cellular components, including T-tubule; Z disc; and sarcoplasmic reticulum membrane. Is active in calyx of Held. Colocalizes with caveola. Is expressed in several structures, including alimentary system; genitourinary system; integumental system; nervous system; and sensory organ. Used to study achalasia and hypertrophic pyloric stenosis. Human ortholog(s) of this gene implicated in Alzheimer's disease; Parkinson's disease; asthma; and cystic fibrosis. Orthologous to human NOS1 (nitric oxide synthase 1). [provided by Alliance of Genome Resources, Jul 2025]
nitric oxide synthase 1 (neuronal) adaptor protein
Enables nitric-oxide synthase binding activity. Predicted to be involved in postsynaptic actin cytoskeleton organization; regulation of heart rate by chemical signal; and regulation of ventricular cardiac muscle cell membrane repolarization. Located in Z disc; mitochondrion; and sarcoplasmic reticul
um membrane. Colocalizes with T-tubule and caveola. Is expressed in several structures, including brain; gallbladder; genitourinary system; spinal cord; and trachea. Human ortholog(s) of this gene implicated in nephrotic syndrome type 22. Orthologous to human NOS1AP (nitric oxide synthase 1 adaptor protein). [provided by Alliance of Genome Resources, Jul 2025]
