  • 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.

  • Immunohistochemistry was performed on normal biopsies of deparaffinized Rat cerebellum tissue. To expose target proteins heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer and microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:200 with a Rabbit Polyclonal Antibody recognizing nNOS (ab3511 ) or without primary antibody (negative control) overnight at 4�C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.
  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of mouse skeletal muscle tissue sections labeling nNOS (neuronal) with ab3511 at 1/400 (left). Antigen retrieval was performed using 10M sodium citrate (pH 6.0) buffer, microwaved for 8-15 minutes. Tissues were blocked in 3% BSA in PBS for 30 minutes at room temperature. A biotin-conjugated secondary antibody was used. Right - negative control.

  • Western blot analysis of nNOS was performed by loading 40 ?g of Mouse (Lane 1) and Rat Brain (Lane 2) tissue lysate onto a 4-12% Bis-Tris polyacrylamide gel. Proteins were transferred to a Nitrocellulose membrane. Membranes were probed with a rabbit polyclonal antibody (ab3511) recognizing nNOS at a dilution of 1:1000.
