Description de la cible

Neurofilament medium polypeptide (UniProt: P12839; also known as NF-M, 160 kDa neurofilament protein, Neurofilament 3, Neurofilament triplet M protein) is encoded by the Nefm (also known as Nef3, Nfm) gene (Gene ID: 24588) in rat. Neurofilaments are intermediate filaments that serve as major elements of the cytoskeleton supporting the axon cytoplasm. They are the most abundant fibrillar components of the axon, being on average 3-10 times more frequent than axonal microtubules. They are built from three intertwined protofibrils, which themselves are composed of two tetrameric protofilament complexes of monomeric proteins. The neurofilament triplet proteins (68/70, 160, and 200 kDa) occur in both the central and peripheral nervous system and are usually neuron specific. The 68/70 kDa NF-L protein can self-assemble into a filamentous structure, however the 160 kDa NF-M and 200 kDa NF-H proteins require the presence of the 68/70 kDa NF-L protein to co-assemble. Neurofilaments contain a number of repeats of the tripeptide KSP (Lys-Ser-Pro) and NF-M is phosphorylated on a number of the serine residues in this motif by protein kinase A and C. Phosphorylation of NF-M results in the formation of interfilament cross bridges that are important in the maintenance of axonal caliber. Deletion of the phosphorylated tail domain of NF-M is reported to inhibit radial growth of axons and reduce their conduction velocities. However, mice expressing NF-M subunits that lack phosphorylation at KSP sites along the tail domain have normal axon calibers and conduction velocities, indicating that the NF-M tail domain, but not tail phosphorylation is crucial for axon radial growth. The level of phosphorylation is shown to be altered developmentally and coincides with a change in the neurofilament function. Mutations in the rod domain region of NF-M have been identified in early onset Parkinson s disease. Also, in the brains of Alzheimer s disease patients, a reciprocal relationship between O-GlcNAcylation and phosphorylation of NF-M has been reported where reduced O-GlcNAcylation is accompanied with increased KSP phosphorylation in NF-M.
