Protein: Alpha-internexin (Alpha-Inx) (66 kDa neurofilament protein) (NF-66) (Neurofilament-66) (P46660)
Organism: Mus musculus (Mouse)
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 NEFL to form the filamentous backbone to which NEFM and NEFH attach to form the cross-bridges (By similarity). May also cooperate with the neuronal intermediate filament protein PRPH to form filamentous networks.
InterPro domains:
- IPR050405: Intermediate filament structural protein (family) [5-477]
- IPR006821: Intermediate filament head, DNA-binding domain (domain) [11-92]
- IPR018039: Intermediate filament protein, conserved site (conserved_site) [393-401]
- IPR039008: Intermediate filament, rod domain (domain) [93-407]
