CC -!- FUNCTION: Neurofilaments usually contain three intermediate filament
CC proteins: NEFL, NEFM, and NEFH which are involved in the maintenance of
CC neuronal caliber. May additionally cooperate with the neuronal
CC intermediate filament proteins PRPH and INA to form neuronal
CC filamentous networks (By similarity). {ECO:0000250|UniProtKB:P08551}.
CC -!- SUBUNIT: Forms homodimers (in vitro) (By similarity). Forms
CC heterodimers with NEFH or NEFM; which can further hetero-oligomerize
CC (in vitro) (By similarity). Forms heterodimers with INA (in vitro) (By
CC similarity). Interacts with ARHGEF28. Interacts with TRIM2.
CC {ECO:0000250, ECO:0000250|UniProtKB:P19527}.
CC -!- SUBCELLULAR LOCATION: Cell projection, axon
CC {ECO:0000250|UniProtKB:P08551}. Cytoplasm, cytoskeleton
CC {ECO:0000250|UniProtKB:P08551}.
CC -!- DOMAIN: The extra mass and high charge density that distinguish the
CC neurofilament proteins from all other intermediate filament proteins
CC are due to the tailpiece extensions. This region may form a charged
CC scaffolding structure suitable for interaction with other neuronal
CC components or ions.
CC -!- PTM: O-glycosylated. {ECO:0000250}.
CC -!- PTM: Phosphorylated in the head and rod regions by the PKC kinase PKN1,
CC leading to the inhibition of polymerization. {ECO:0000250}.
CC -!- PTM: Ubiquitinated in the presence of TRIM2 and UBE2D1. {ECO:0000250}.
CC -!- MASS SPECTROMETRY: Mass=62600; Method=MALDI;
CC Evidence={ECO:0000269|PubMed:14967049};
CC -!- MISCELLANEOUS: NF-L is the most abundant of the three neurofilament
CC proteins and, like the other nonepithelial intermediate filament
CC proteins, it can form homomeric 10-nm filaments.
CC -!- SIMILARITY: Belongs to the intermediate filament family.
CC {ECO:0000255|PROSITE-ProRule:PRU01188}.
