| Molecular Weight | The recombinant rat GFRA1 comprises 432 amino acids and predicts a molecular mass of 48 kDa. The apparent molecular mass of the rat GFRA1 is approximately 58-65 kDa in SDS-PAGE under reducing conditions due to glycosylation. |
| predicted N | Asp 25 |
| SDS-PAGE |  |
| Purity | > 97 % as determined by SDS-PAGE |
| Protein Construction | A DNA sequence encoding the rat GFRA1 (Q62997-1) (Met 1-Leu 445) was expressed, fused with a polyhistidine tag at the C-terminus. |
| Bio-activity | 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 Rat GDNF. |
| Research Area | Cardiovascular |Angiogenesis |Cytokine & Receptor |Transforming Growth Factor Beta (TGF-beta) Superfamily |TGF-beta Superfamily Receptors |
| 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. |
| 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. |
