| Gene Symbol | NEFH |
| Gene Full Name | neurofilament, heavy polypeptide |
| Background | Neurofilaments are type IV intermediate filament heteropolymers composed of light, medium, and heavy chains. Neurofilaments comprise the axoskeleton and functionally maintain neuronal caliber. They may also play a role in intracellular transport to axons and dendrites. This gene encodes the heavy neurofilament protein. This protein is commonly used as a biomarker of neuronal damage and susceptibility to amyotrophic lateral sclerosis (ALS) has been associated with mutations in this gene. [provided by RefSeq, Oct 2008] |
| Function | Neurofilaments usually contain three intermediate filament proteins: L, M, and H which are involved in the maintenance of neuronal caliber. NF-H has an important function in mature axons that is not subserved by the two smaller NF proteins. [UniProt] |
| Research Area | Neuroscience antibody; Signaling Transduction antibody; Neurofilament antibody; Intermediate Neurofilament antibody |
| Calculated MW | 112 kDa |
| PTM | There are a number of repeats of the tripeptide K-S-P, NFH is phosphorylated on a number of the serines in this motif. It is thought that phosphorylation of NFH results in the formation of interfilament cross bridges that are important in the maintenance of axonal caliber. Phosphorylation seems to play a major role in the functioning of the larger neurofilament polypeptides (NF-M and NF-H), the levels of phosphorylation being altered developmentally and coincidentally with a change in the neurofilament function. Phosphorylated in the head and rod regions by the PKC kinase PKN1, leading to the inhibition of polymerization. |

Immunocytochemistry: Rat Mixed neuron / glia cultures stained with ARG10761 anti-Neurofilament NF-H antibody (green) and co-stained with chicken antibody to neurofilament subunit NF-L (red). Axons contain phosphorylated NF-H and NF-L so appear yellow, while dendrites and perikarya only contain NF-L and so appear red. DNA is shown in blue.

Immunohistochemistry: Frozen section of Mouse hippocampus stained with ARG10761 anti-Neurofilament NF-H antibody (red) at 1:2000 dilution and costained with ARG10723 anti-Myelin Basic Protein antibody [7G7] (green) at 1:5000 dilution. DAPI (blue) for nuclear staining. (Sample preparation: Following transcardial perfusion with 4% paraformaldehyde, brain was post fixed for 24 hours, cut to 45 µM, and free-floating sections were stained with above antibodies.)
The NF-H antibody labels a network of axons of different neurons, while the Myelin Basic Protein antibody stains myelin sheath around these axons.

Western blot: Rat brain, Rat spinal cord, Mouse brain and Mouse spinal cord lysates stained with ARG10761 anti-Neurofilament NF-H antibody (green) at 1:10000 dilution.
Strong band at about 220 kDa corresponds to the phosphorylated axonal form of the NF-H subunit. Smaller proteolytic fragments of NF-H are also detected.
