Gene Full Name neurofilament, medium 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 medium neurofilament protein. This protein is commonly used as a biomarker of neuronal damage. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [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. [UniProt]
PTM There are a number of repeats of the tripeptide K-S-P, NFM is phosphorylated on a number of the serines in this motif. It is thought that phosphorylation of NFM 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 ARG10724 anti-Neurofilament NF-M antibody (red) and co-stained with Mouse monoclonal antibody [1G10] to Fox1 (green). ARG10724 anti-Neurofilament NF-M antibody stains axonal, dendritic and perikaryal profiles of neurons cleanly and specifically. Like antibody to Fox3 / NeuN, the Fox1 antibody binds to the nuclei of neurons only. DNA is shown in blue with DAPI.

    Immunohistochemistry: Frozen section of Rat cerebellum stained with ARG10724 anti-Neurofilament NF-M antibody (red) at 1:2000 dilution and costained with ARG10715 anti-GAP43 antibody [3H14] (green) at 1:2000 dilution. (Sample preparation: Following transcardial perfusion of Rat with 4% paraformaldehyde, brain was post fixed for 24 hours, cut to 45 µM, and free-floating sections were stained with the above antibodies.)

    The NF-M antibody strongly labels neuronal processes throughout the cerebellum, while the GAP43 antibody stains predominantly synaptic regions in the molecular layer.
