Human GFR alpha-2, His Tag (GF2-H5225) is expressed from human 293 cells (HEK293). It contains AA Ser 22 - Ser 441 (Accession # NP_001486.4).
Predicted N-terminus: Ser 22
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 47.6 kDa. The protein migrates as 60-70 KDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>97% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

GDNF family receptor alpha-2 (GFRA2) is also known as GDNF receptor beta, Neurturin receptor alpha, RET ligand 2, TGF-beta-related neurotrophic factor receptor 2, is a cell membrane protein which belongs to the GDNFR family. Glial cell line-derived neurotrophic factor (GDNF) and neurturin (NTN) are two structurally related, potent neurotrophic factors that play key roles in the control of neuron survival and differentiation. GDNF is a glycosylated, disulfide-bonded homodimer that is distantly related to the TGF-beta superfamily of growth factors. Three receptors for these factors, GFRα-1, GFRα-2 and GFRα-3 have been identified. The isoform 1 of GFRA2 is found in both brain and placenta. GFRA2 mediates the NRTN-induced autophosphorylation and activation of the RET receptor and also able to mediate GDNF signaling through the RET tyrosine kinase receptor. GFRA2 mediates the NRTN-induced autophosphorylation and activation of the RET receptor. It can also mediate GDNF signaling through the RET tyrosine kinase receptor.
