Mouse GFR Alpha-3/GFRA3 HEK293 Overexpression Lysate: 产品信息
This Mouse GFR Alpha-3/GFRA3 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of GFR Alpha-3/GFRA3 protein (Cat: 50901-M02H) from the overexpression lysate was verified.
A DNA sequence encoding the mouse GFRA3 (O35118) (Met 1-Arg 379), was fused with the Fc region of human IgG1 at the C-terminus.
The secreted recombinant mouse GFRA3 Fc is a disulfide-linked homodimer. The reduced monomer comprises 592 amino acids and has a calculated molecular mass of 66.2 kDa. The apparent molecular mass of rmGFRA3/Fc monomer is approximately 70 kDa in SDS-PAGE under reducing conditions.

Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
Glial cell line derived neurotrophic factor (GDNF) Family Receptor Alpha 3 (GFRA3) or GDNFRa3 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. GFRA3 / GDNFRa3 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. The neurotrophic growth factor artemin binds selectively to GDNF family receptor α3 (GFRA3 / GDNFRa3), forming a molecular complex with the co-receptor RET which mediates downstream signaling. This signaling pathway has been demonstrated to play an important role in the survival and maintenance of nociceptive sensory neurons and in the development of sympathetic neurons.
