GFRA2/GDNFR-alpha-2 protein acts as a receptor for neurotrophic factors and promotes NRTN-induced autophosphorylation and RET receptor activation. It also mediates GDNF signaling through the RET tyrosine kinase receptor. GFRA2/GDNFR-alpha-2 Protein, Mouse (HEK293, His) is the recombinant mouse-derived GFRA2/GDNFR-alpha-2 protein, expressed by HEK293 , with C-His labeled tag.
