GFR Alpha-1/GFRA1 Protein, Hum

蛋白长度：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.

性质：

表达系统：HEK293 Cells

种属：Human

氨基酸序：Met1-Ser424

标签类型：C-His

分子量：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.

活性：Immobilized Recombinant Human GDNF Protein(Cat:PH51024M0) at 2 μg/mL (100 μL/well) can bind Recombinant Human GFRA1 / GFRα1 / GDNFRA Protein (His Tag) (Cat:PH51063M2), the ECis 15-48 ng/mL.

内毒素：< 1.0 EU per μg of the protein as determined by the LAL method.

基因名称：GDNF family receptor alpha 1

通用名：GFRA1

蛋白序参考：NP_665736.1

总结：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-a) 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.

形式：Lyophilized

纯度：> 98 % as determined by SDS-PAGE.

储存条件：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. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.

储存溶液：Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
