  • Positive control
    • This antibody gave a positive signal in mouse forebrain and mouse spinal cord tissue lysates. HeLa whole cell lysate was used as a negative control. nNOS is widely expressed in the nervous system: cerebrum, olfactory bulb, hippocampus, midbrain, cerebellum, pons, medulla oblongata, and spinal cord. It is also found in skeletal muscle, spleen, heart, kidney, and liver.

Target

  • 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
    modifications
    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.

    This blot was produced using a 3-8% Tris Acetate gel under the TA buffer system. The gel was run at 150V for 60 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes. The membrane was then blocked for an hour using 2% Bovine Serum Albumin before being incubated with ab16650 overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution ab133406.

  • Immunostaining using Rabbit polyclonal to nNOS (neuronal) (phospho S847) (ab16650) on rat brain tissue sections (30 micron free floating). ab16650 was used at a dilution of 1/3000 and incubated for 18 hours at RT (in PBS triton 0.3%). Secondary Antibody Goat anti-rabbit alexa Fluor 488 was used at a dilution of 1/1000. The image shows cytoplasmic staining of CNS neurons with ab16650 in naïve rats; the staining being observed in the soma and processes of these neurons. The staining was quenched by pre-incubation with peptide against phospho S847 (ab16981), but not by the control peptide (ab57047) indicating that ab16650 is specific for nNos phosphorylated at S847. Protocol: Rats were perfused-fixed with 4% paraformaldehyde. Tissues were post-fixed overnight in the same fixative and then cryoprotected in 20% sucrose overnight. Following embedding in OCT and freezing, tissues were cut and immunostained using the 'free floating’ technique.
  • ab16650 staining nNOS (neuronal) (phospho S847) in 16 µm thick sections of Apteronotus leptorhynchus by Immunohistochemistry (Frozen sections).
    Tissue was fixed in 2% paraformaldehyde, permeabilized using 0.3% Triton X-100, blocked with 3% sheep serum, 1% BSA, 1% teleostean gelatine in TBS for 1 hour at 24°C and then incubated with ab16650 at a 1/100 dilution for 18 hours at 4°C. The secondary used was an Alexa-Fluor 488 conjugated goat anti-rabbit polyclonal used at a 1/200 dilution.
