  • Target

    • FunctionNeurofilaments 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.
    • Involvement in diseaseDefects in NEFH are a cause of susceptibility to amyotrophic lateral sclerosis (ALS) [MIM:105400]. ALS is a neurodegenerative disorder affecting upper and lower motor neurons, and resulting in fatal paralysis. Sensory abnormalities are absent. Death usually occurs within 2 to 5 years. The etiology is likely to be multifactorial, involving both genetic and environmental factors.
    • Sequence similaritiesBelongs to the intermediate filament family.
    • Post-translational
      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 coincident with a change in the neurofilament function.
      Phosphorylated in the Head and Rod regions by the PKC kinase PKN1, leading to inhibit polymerization.

    • Anti-200 kD Neurofilament Heavy antibody [AH1] (ab78158) at 1/10000 dilution + Crude rat spinal cord extract
      developed using the ECL technique

      Predicted band size : 112 kDa
    • Mixed neuron/glial cultures stained with ab78158 (green), at 1/1000 dilution, and also stained with a rabbit polyclonal antibody to neurofilament NF-L (red). The NF-L antibody stains neurofilaments in both axons and dendrites, and so can reveal neuronal cell bodies, while ab78158 binds to only heavily phosphorylated forms of 200 kD Neurofilament Heavy which are localized to mature axonal neurofilaments. In this image a few axons course from left to right and top to bottom- since they contain both NF-L and phosphorylated 200 kD Neurofilament Heavy they appear golden in color. Blue shows the distribution of DNA.
