AU042498

Catalog Number P50171-M08H
Organism Species Mouse
Host Human Cells
Synonyms AU042498
Molecular Weight The secreted recombinant mouse GFRα1consists of 412 amino acids and has a calculated molecular mass of 46.3 kDa. As a result of glycosylation, the recombinant protein migrates as an approximately 55-60 kDa protein in SDS-PAGE under reducing conditions.

Purity > 98 % as determined by SDS-PAGE
Protein Construction A DNA sequence encoding the extracellular domain (Met 1-Ser 425) of mouse GFRα1 isoform beta (AAB86600.1) was expressed with a C-terminal polyhistidine tag.
Bio-activity 1. Measured in a cell proliferation assay using SH‑SY5Y human neuroblastoma cells.
The ED50 for this effect is typically 0.3-1.5 μg/mL in the presence of 40 ng/mL Recombinant Human GDNF.
2. Measured by its ability to bind with human GDNF (P10561-HNCH) in a functional ELISA.

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.
