Protein attributes

Sequence length	499 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Class-IV neuronal intermediate filament that is able to self-assemble. It is involved in the morphogenesis of neurons. It may form an independent structural network without the involvement of other neurofilaments or it may cooperate with NF-L to form the filamentous backbone to which NF-M and NF-H attach to form the cross-bridges.
Tissue specificity	Found predominantly in adult CNS.
Developmental stage	Expressed in brain as early as the 16th week of gestation, and increased rapidly and reached a steady state level by the 18th week of gestation.
Post-translational modification	O-glycosylated By similarity.
Sequence similarities	Belongs to the intermediate filament family.
