GFRA1 is a co-receptor that recognizes the GDNF ligand family and is involved in the regulation of proliferation, differentiation and migration of neuronal cells. GFRA1 promotes autophagy through the SRC-AMP-activated protein kinase (AMPK) signaling pathway, thereby contributing to the development of cisplatin-induced chemotherapy resistance to osteosarcoma. GFRA1/GDNFR-alpha-1 Protein, Canine (HEK293, His) is the recombinant canine-derived GFRA1/GDNFR-alpha-1 protein, expressed by HEK293 , with C-His labeled tag.
