General description

In humans, nitric oxide synthase 1 (NOS1) or neuronal nitric acid synthase (nNOS) is localized to the sarcoplasmic reticulum. The gene encoding it is, localized on human chromosome 12q24.22. In rats, the protein is present in perivascular nerves supplying the cerebral vasculature. The gene encoding it is localized on rat chromosome 12q16.

The nitric oxide synthase (NOS) isoform found in neurons is a 150-160 kDa protein. It is also termed brain NOS, NOS1, neuronal NOS (nNOS or bNOS, neuronal constitutive NOS or Ca2+-regulated NOS (cNOS, ncNOS). The nNOS or NOS1 gene is mapped to human chromosome 12q24.22. bNOS is present in skeletal muscle, central, peripheral neurons and neuronal cell bodies. Human bNOS and endothelial nitric oxide synthase (eNOS) share 52% amino acid identity, and rat and human bNOS share 93% amino acid identity. Structurally NOS exists as homodimers. The N-terminal region comprises heme and calmodulin binding sites. The reduced nicotinamide adenine dinucleotide phosphate (NADPH) and flavins binding regions are localized in C-terminal region.


The antibody is specific for nitric oxide synthase (NOS) derived from brain. It does not recognize NOS derived from activated macrophages (iNOS) and endothelial cells (eNOS).


synthetic peptide corresponding to nitric oxide synthase (NOS) of rat brain origin (bNOS, amino acids 1409-1429) conjugated to KLH. The immunogen sequence differs from the human bNOS by a single amino acid residue.

Biochem/physiol Actions

Nitric oxide synthase (NOS), brain (nNOS or bNOS) mediates long-term regulation of synaptic transmission (long-term potentiation, long-term inhibition). It catalyzes the production of nitric oxide (NO) from L-arginine. The NO mediates neurovascular coupling and is associated with neuronal plasticity and pain signal transmission. nNOS regulates blood pressure, relaxation of smooth muscle and vasodilatation via peripheral nitrergic nerves. nNOS is complexed to dystrophin. However, in Duchenne muscular dystrophy (DMD), the skeletal muscle sarcolemma is devoid of nNOS.
