NF-M Recombinant Rabbit Monoclonal Antibody [JM11-20] (ET1703-57)

UNIPROT #

P07197

PROTEIN NAME

NEFM

SYNONYMS

150kDa medium antibody;NEF3 antibody;NEFM antibody;Neurofilament 3 antibody;NF160 antibody;NFM antibody

SEQUENCE SIMILARITIES

Belongs to the intermediate filament family.

POST-TRANSLATIONAL MODIFICATION

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.

SUBCELLULAR LOCATION

Cell projection, Cytoplasm, Cytoskeleton, Intermediate filament.

FUNCTION

Neurofilament-M (NF-M), for neurofilament medium polypeptide, a member of the intermediate filament family, is a major component of neuronal cytoskeletons. Neurofilaments are dynamic structures; they contain phosphorylation sites for a large number of protein kinases, including protein kinase A, protein kinase C, cyclin-dependent kinase 5, extracellular signal regulated kinase, glycogen synthase kinase-3, and stress-activated protein kinase gamma. In addition to their role in the control of axon caliber, neurofilaments may affect other cytoskeletal elements, such as microtubules and actin filaments. Changes in neurofilament phosphorylation or metabolism are frequently observed in neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), Parkinson's disease, and Alzheimer's disease.
