This cysteine rich domain is found in multiple copies in GNDF and GAS1 proteins. GDNF and neurturin (NTN) receptors are potent survival factors for sympathetic, sensory and central nervous system neurons [2]. GDNF and neurturin promote neuronal survival by signaling through similar multicomponent receptors that consist of a common receptor tyrosine kinase and a member of a GPI-linked family of receptors that determines ligand specificity [3].
