The GDNF family receptor-α (GFRα) proteins are a group of co-receptors which form complexes with GDNF-family ligands (GFLs) to activate RET, the receptor of the GFLs.^[1] The GFRα co-receptors include the following:

GFRα1 – preference for GDNF
GFRα2 – preference for neurturin
GFRα3 – preference for artemin
GFRα4 – preference for persephin
GFRAL - receptor for GDF15
