CC -!- FUNCTION: Class-IV neuronal intermediate filament that is able to self-
CC assemble. It is involved in the morphogenesis of neurons. It may form
CC an independent structural network without the involvement of other
CC neurofilaments or it may cooperate with NEFL to form the filamentous
CC backbone to which NEFM and NEFH attach to form the cross-bridges. May
CC also cooperate with the neuronal intermediate filament protein PRPH to
CC form filamentous networks (By similarity).
CC {ECO:0000250|UniProtKB:P46660}.
CC -!- SUBUNIT: Forms homodimers (in vitro) (By similarity). Forms
CC heterodimers with NEFL, NEFM or NEFH (in vitro) (By similarity).
CC {ECO:0000250|UniProtKB:P23565}.
CC -!- INTERACTION:
CC Q16352; P05067: APP; NbExp=3; IntAct=EBI-366258, EBI-77613;
CC Q16352; P37840: SNCA; NbExp=3; IntAct=EBI-366258, EBI-985879;
CC -!- TISSUE SPECIFICITY: Found predominantly in adult CNS.
CC -!- DEVELOPMENTAL STAGE: Expressed in brain as early as the 16th week of
CC gestation, and increased rapidly and reached a steady state level by
CC the 18th week of gestation.
CC -!- PTM: O-glycosylated. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the intermediate filament family.
CC {ECO:0000255|PROSITE-ProRule:PRU01188}.
