This is the C-terminal domain of Neuron-derived Neurotrophic Factor (NDNF). NDNF is a glycosylated and disulfide-bonded secreted protein expressed in brain and spinal cord that promotes migration and neurite growth of hippocampal neurons. It also promotes endothelial cell survival, vessel formation and plays an important role in the process of revascularization. This domain contains the second fibronectin type III domain (FnIII) present in NDNF and one of the two potential consensus sites for N-linked glycosylation [1,2].
