Background: Members of the glial cell line-derived neurotrophic factor (GDNF) family, including GDNF and neurturin (NTN), play key roles in the control of vertebrate neuron survival and differentiation. Physiological responses to NTN require the presence of a novel glycosylphosphadidylinositol linked protein NTNRα, which is a cell surface receptor for NTN. The cDNAs encoding NTNRa from human, rat, chicken, and mouse have been cloned recently. NTNRα was also termed GDNFRβ, Ret ligand 2 (RETL2) or TGFβ-related neurotrophic factor receptor 2 (TrnR2) and nominated as GFRα-2 recently. GFRα-2 binds NTN and mediates activation of RET receptor tyrosine kinase by both NTN and GDNF. Thus, NTN, GFRα-2, and the Ret PTK form a complex to transduce NTN signal and to mediate NTN function.
Positive Control: Receptor for neurturin. Mediates the NRTN-induced autophosphorylation and activation of the RET receptor. Also able to mediate GDNF signaling through the RET tyrosine kinase receptor. Positive Control: HeLa Cell Lysate.
Immunogen: Peptide corresponding to amino acids 377 to 391 of human GFRalpha;-2. The amino acid sequences of immunogenic peptide are identical to those of mouse and rat.
Purification Method: Antigen Immunoaffiinity Purification.
Formulation: Provided as solution in phosphate buffered saline with 0.02% sodium azide.
