Glial Cell line-derived Neurotrophic Factor Receptor alpha 2 Protein (recombinant human)

Protein Construction: Recombinant Human Glial Cell line-derived Neurotrophic Factor Receptor alpha 2 is produced by our Mammalian expression system and the target gene encoding Ser22-Ser441 is expressed with a 6His tag at the C-terminus. Sequence: Ser22-Ser441. Fusion tag: C-6His Endotoxin: < 1.0 EU per µg as determined by the LAL method. Apparent Molecular Mass: 80 kDa. Protein function: Members of the glial cell line-derived neurotrophic factor (GDNF) family, including GDNF and Neurturin, play key roles in the control of vertebrate neuronal survivial and differentiation. GDNF is a glycosylated, disulfide-bonded homodimer that is distantly related to the TGF superfamily of growth factors. Three receptors for these factors, GFRa-1, GFRa-2, and GFRa-3 have been identified. The receptors do not contain transmembrane domains and are attached to the cell membrane by glycosyl-phosphoinositol linkage. Both GFRa-1 and GFRa-2 have been shown to mediate the GDNF-dependent and Neurturin-dependent phosphorylation and activation of the tyrosine kinase Ret. GFR-3 is expressed only during development. GFRa-2 binds Neurturin and mediates activation of RET receptor tyrosine kinase by both Neurturin and GDNF. Protein function: 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. [The UniProt Consortium]
