Function
Nerve growth factor (NGF) belongs to the family of neurotrophins. NGF promotes survival and differentiation of sensory and sympathetic neurons. NGF signaling furthers neuroprotective and repair functions[1]. NGF interacts with 2 transmembrane receptors - TrkA and p75.
Relevance
Increased cerebrospinal fluid levels of proNGF mark the onset of mild cognitive impairment and the transition to Alzheimer disease suggest that NGF is a potential Alzheimer biomarker[2].
Structural highlights
The 3D structure of the complex between human NGF and one of its receptors - TrkA - is shaped like a crab with the NGF homodimer serving as the crab's body.
