Anti-Human GFR α-3 (G684-GRP)

GDNF family receptor alpha 3, also known as GFRA3 is a glycosylphosphatidylinositol(GPI)-linked cell surface receptor and a member of the GDNF receptor family. It forms a signaling receptor complex with RET tyrosine kinase receptor and binds the ligand, artemin. GFRalpha3 preferentially binds the newest member of the glial-derived neurotrophic factor family of ligands, artemin. The major site of GFRalpha3 expression is in the dorsal root ganglion. GFRalpha3 artemin neurons are immunopositive for markers expected of nociceptors and include a subset of neurons distinct from the GDNF-responsive population.1
