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].

Structural analysis indicate that the ligand-binding RET ectodomain (RET-ECD) contains four consecutive cadherin-like domains (CLD1-CLD4) followed by a membrane-proximal cysteine-rich domain (CRD). This entry relates to the Cysteine Rich Domain (CRD) domain [1,2].

Structural analysis indicate that RET contains four consecutive cadherin-like domains (CLD). This entry relates to the first CLD at the N-terminal. Several regions within RET-CLD1 have been shown to be important for ligand-coreceptor binding. CLD1 and CLD2 have a distinctive clamshell shape and CLD1 is essential for CLD2 folding. CLD1 contains 2 sites for GDNF receptor alpha 1 binding [1].

Structural analysis indicate that RET contains four consecutive cadherin-like domains (CLD). This entry relates to CLD3. Classical cadherin calcium-coordinating motifs can be found between CLD2 and CLD3 [1].
