Overview
NFL one of the three (L, M, and H) intermediate filament proteins that form neurofilaments. Neurofilaments are involved in the maintenance of neuronal caliber. NF-L is the most abundant of the three neurofilament proteins. Defects cause Charcot-Marie-Tooth disease type 1F (CMT1F). Note: This description may include information from UniProtKB.
Protein type: Cytoskeletal protein
Cellular Component: TSC1-TSC2 complex; axon; neurofilament; cytosol
Molecular Function: protein C-terminus binding; identical protein binding; protein binding; structural constituent of cytoskeleton
Biological Process: synaptic transmission; axon transport of mitochondrion; neurofilament bundle assembly; intermediate filament organization; anterograde axon cargo transport; retrograde axon cargo transport
Reference #:  P07196 (UniProtKB)
Alt. Names/Synonyms: 68 kDa neurofilament protein; CMT1F; CMT2E; FLJ53642; light molecular weight neurofilament protein; NEFL; Neurofilament light polypeptide; neurofilament protein, light chain; neurofilament subunit NF-L; Neurofilament triplet L protein; neurofilament, light polypeptide; neurofilament, light polypeptide 68kDa; neurofilament-light; NF-L; NF68; NFL
Gene Symbols: NEFL
Molecular weight: 61,517 Da
Basal Isoelectric point: 4.64  Predict pI for various phosphorylation states
