靶點詳情

功能：

Neurofilaments usually contain three intermediate filament proteins: NEFL, NEFM, and NEFH which are involved in the maintenance of neuronal caliber. May additionally cooperate with the neuronal intermediate filament proteins PRPH and INA to form neuronal filamentous networks.
基因功能參考文獻：
1. NF-L may be involved in severity of neuronal injury following traumatic brain injury PMID: 27819296
2. CSF neurofilament light chain protein is an accurate marker for distinguishing Alzheimer's disease patients from healthy controls. PMID: 28527630
3. Cerebrospinal fluid neurofilament protein light is a useful tool for determining disease intensity in frontotemporal dementia and motor neuron disease patients. PMID: 28631955
4. Our results suggest that plasma NFL levels may not be a useful biomarker for the diagnosis of prodromal and dementia stages of AD. PMID: 28428015
5. In this Chinese Han population a novel Charcot-Marie-Tooth disease-associated gene mutations of NEFL (c.280C>T) was discovered. PMID: 27862672
6. We conclude that low BDNF and high LCN2 and NF-L levels are associated with Multiple Sclerosis (MS) pathogenesis, and high IGFBP1level is a biomarker for female MS only, suggesting different MS progression pathways between the sexes. LCN2 is a candidate predictor of response to natalizumab treatment, and NF-L is a candidate predictor of clinically isolated syndrome's (CIS) conversion into MS. PMID: 29108879
7. This study showed tat Serum NfL concentration is increased in familial Alzheimer disease prior to symptom onset and correlates with measures of disease stage and severity. Serum NfL may thus be a feasible biomarker of early AD-related neurodegeneration. PMID: 29070659
8. Results show that both alphaS and NFL can be phosphorylated by CKII, PLK2 and PLK3, but Ser129 in alphaS is a preferential site for PLK2 and PLK3, demonstrating higher phosphorylation efficiency. Comparatively, CKII preferentially phosphorylates Ser473 in NFL and this site can be phosphorylated by PLK1, 2 and 3, but these enzymes prefer to modify other sites within NFL. PMID: 27503460
9. fL is a weak independent risk factor in clinically isolated syndromes for conversion to multiple sclerosis. Its role as an axonal damage biomarker may be more relevant as suggested by its association with medium-term brain volume changes. PMID: 27521440
10. Results from 2 independent prospective cohort studies show that serum NFL is a sensitive and dynamic biomarker for axonal injury in concussive traumatic brain injury. The marker should be useful to detect and monitor CNS injury in concussion PMID: 28404801
11. Findings support the potential value of serum NfL as a marker of neuroaxonal injury in early multiple sclerosis. Its reduction over time could represent regression to the mean, or a possible treatment effect of IFN-beta-1a. Association with whole brain atrophy and formation of acute white matter lesions has implications to use serum NfL as a biomarker of the overall consequences of brain damage and ongoing disease acti... PMID: 28148632
12. Higher serum NfL concentrations are associated with more rapid brain atrophy and may therefore reflect disease intensity in dementia (FTD). Because blood sampling is less invasive and has better patient acceptability than lumbar puncture, serum NfL may provide important prognostic information and prove to be a useful outcome measure for clinical trials in FTD. PMID: 27581216
13. We conclude that the NEFL N98S mutation is associated with a dominant intermediate Charcot-Marie-Tooth disease phenotype characterized by early-onset sensorimotor neuropathy delaying motor milestones, which may evolve into a severe and complex clinical picture including cerebellar ataxia. PMID: 26645395
14. Plasma Concentration of the Neurofilament Light Protein (NFL) is a Biomarker of CNS Injury in HIV Infection PMID: 26870824
15. The results showed an important role for miR-25 in regulating NEFL expression in Glioblastoma multiforme. PMID: 26209061
16. Finally, we demonstrated that NEFL inhibited the NF-kappaB pathway, thereby suppressing the expression of uPA and decreasing NSCLC invasiveness and migration. PMID: 26801564
17. Cerebrospinal fluid NFL concentration is increased by the early clinical stage of Alzheimer's Disease. PMID: 26524180
18. The miR-381-NEFL axis is important for temozolomide resistance in glioblastoma multiforme. PMID: 25605243
19. The results od this study concluded that NEFL E396K mutation may manifest with a novel DI-CMT phenotype, characterized by simultaneous involvement of the peripheral and central nervous system. PMID: 25877835
20. Suggest monitoring the serum level of antibodies against the NF-L chain as a predictive biomarker of treatment response in multiple sclerosis. PMID: 24515731
21. a novel heterozygous missense mutation c.1166A>G (p.Y389C) in the gene encoding the light-chain neurofilament protein was identified in 4 patients resulting in hereditary motor and sensory neuropathy with pyramidal signs phenotype. PMID: 25583183
22. Data suggest that, while lacking a stable structure, NFL-TBS.40-63 peptide (a peptide derived from light neurofilament protein) preferentially binds on a specific single site located near C-terminal end of beta-tubulin. PMID: 26016807
23. Blood-derived NfL level is an easily accessible biomarker with prognostic value in ALS. PMID: 25934855
24. Data indicate that the N terminus of Pro-EMAP II binds to its C terminus, arginyl-tRNA synthetase, and the neurofilament light subunit. PMID: 25724651
25. an NEFL mutation in a family clinically manifesting congenital myopathy PMID: 25264603
26. NEFL overexpression also enhanced differentiation. PMID: 25312269
