Neurofilament light polypeptide (NFL), also known as neurofilament light chain, is a neurofilament protein that in humans is encoded by the NEFL gene.[5][6] Neurofilament light chain is a biomarker that can be measured with immunoassays in cerebrospinal fluid and plasma and reflects axonal damage in a wide variety of neurological disorders.[7][8] It is a useful marker for disease monitoring in amyotrophic lateral sclerosis,[9] multiple sclerosis,[10] Alzheimer's disease,[11][12] and more recently Huntington's disease.[13]

It is associated with Charcot–Marie–Tooth disease 1F and 2E.[5]

Interactions

NFL has been shown to interact with:

MAP2,[14]
Protein kinase N1,[15] and
TSC1.[16]
