  • Function
    Produces nitric oxide (NO) which is a messenger molecule with diverse functions throughout the body. In the brain and peripheral nervous system, NO displays many properties of a neurotransmitter. Probably has nitrosylase activity and mediates cysteine S-nitrosylation of cytoplasmic target proteins such SRR.
  • Tissue specificity
    Isoform 1 is ubiquitously expressed: detected in skeletal muscle and brain, also in testis, lung and kidney, and at low levels in heart, adrenal gland and retina. Not detected in the platelets. Isoform 3 is expressed only in testis. Isoform 4 is detected in testis, skeletal muscle, lung, and kidney, at low levels in the brain, but not in the heart and adrenal gland.
  • Sequence similarities
    Belongs to the NOS family.
    Contains 1 FAD-binding FR-type domain.
    Contains 1 flavodoxin-like domain.
    Contains 1 PDZ (DHR) domain.
  • Domain
    The PDZ domain in the N-terminal part of the neuronal isoform participates in protein-protein interaction, and is responsible for targeting nNos to synaptic membranes in muscles. Mediates interaction with VAC14.
  • Post-translational
    Ubiquitinated; mediated by STUB1/CHIP in the presence of Hsp70 and Hsp40 (in vitro).
  • Cellular localization
    Cell membrane > sarcolemma. Cell projection > dendritic spine. In skeletal muscle, it is localized beneath the sarcolemma of fast-twitch muscle fiber by associating with the dystrophin glycoprotein complex. In neurons, enriched in dendritic spines.
  • Information by UniProt


  • Ab41773 (at concentrations of 0.25, 0.5 and 1 µg/ml) blocking the labeling of phsopho-nNOS S1416 by ab5583 (1/500) in mouse tissue sections (paraventricular nuclei of the hypotalamus) by immunohistochemistry (frozen sections). A Biotin-conjugated donkey anti-rabbit IgG polyclonal (1/1000) was used as the secondary antibody.

Review text: Peptide used to block the phospho-nNOS S1416 labeling in mouse brain sections, using immunohistochemistry (peroxidase reaction using DAB).
It completely neutralized the phospho-nNOS labeling in the three concentrations used (1.0, 0.5 and 0.25 µg/mL). The dilution of the primary antibody was 1:500.
The results using this blocking peptide can be found in:
