Human GFRA1 / GFRα1 / GDNFRA Protein (His Tag)

DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Human GFRA1 Protein Product Information
Protein Construction:A DNA sequence encoding the human GFRα1 without the propeptide (NP_665736.1) (Met 1-Ser 424) was fused with the a polyhistidine tag at the C-terminus.
Expressed Host:Human Cells
Shipping:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
Human GFRA1 Protein QC Testing
Purity:> 98 % as determined by SDS-PAGE
Bio-Activity:1. Measured in a cell proliferation assay using SH‑SY5Y human neuroblastoma cells. The ED50 for this effect is typically 0.2-1 μg/mL in the presence of 40 ng/mL Recombinant Human GDNF.
2. Measured by its ability to bind human GDNF (native) in functional ELISA.
Endotoxin:< 1.0 EU per μg of the protein as determined by the LAL method
Stability:Samples are stable for up to twelve months from date of receipt at -70℃
Predicted N Terminal:Asp 25
Molecule Mass:The recombinant human GFRα1 consists of 411 amino acids after removal of the signal peptide and predicts a molecular mass of 46 kDa. As a result of glycosylation, the rhGFRα1 migrates as an approximately 55-60 kDa protein in SDS-PAGE under reducing conditions.
Formulation:Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
2. Please contact us for any concerns or special requirements.

GFRA1 Background

Glial cell line derived neurotrophic factor (GDNF) Family Receptor Alpha 1 (GFRA1) is a member of the GDNF receptor family. It is a glycosylphosphatidylinositol (GPI)-linked cell surface receptor for both GDNF and NTN, and mediates activation of the RET tyrosine kinase receptor. GFRA1 is a potent survival factor for central and peripheral neurons, and is essential for the development of kidneys and the enteric nervous system. Glial cell line-derived neurotrophic factor (GDNF) and neurturin (NTN) are its binding ligand which are two structurally related, potent neurotrophic factors that play key roles in the control of neuron survival and differentiation. GDNF promotes the formation of a physical complex between GFRA/GDNFRa and the orphan tyrosin kinase receptor Ret, thereby inducing its tyrosine phosphorylation. The RET is a receptor tyrosine kinase representing the signal-transducing molecule of a multisubunit surface receptor complex for the GDNF, in which GFRA / GDNFRa acts as the ligand-binding component. GDNF, a distantly related member of the transforming growth factor-β (TGF-â) superfamily, and its receptor components: GFRA1, Ret and neural cell adhesion molecule (NCAM) have been recently reported to be expressed in the testis and to be involved in the proliferation regulation of immature Sertoli cells.
