Scientific Data

Western Blot Detection of Human GFRa-3/GDNF Ra-3 antibody by Western Blot. View Larger

Detection of Human GFR alpha ‑3/GDNF R alpha ‑3 by Western Blot. Western blot shows lysates of human stomach tissue and human small intestine tissue. PVDF membrane was probed with 0.2 µg/mL of Goat Anti-Human GFRa-3/GDNF Ra-3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF670) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). Specific bands were detected for GFRa-3/GDNF Ra-3 at approximately 55 and 65 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: GFR alpha-3/GDNF R alpha-3

Glial cell line-derived growth factor (GDNF), neurturin (NTN), persephin (PEP) and artemin (ART), distant members of the TGF-beta  superfamily, are neurotrophic factors for a variety of neuronal populations in the central and peripheral nervous systems. The bioactivities of these neurotrophic factors are mediated through a receptor complex composed of the non ligand-binding signaling subunit (c-Ret receptor tyrosine kinase) and one of four ligand binding cysteine-rich glycosyl-phosphatidylinositol (GPI)-linked cell surface proteins (GFR alpha -1, 2, 3 or 4). These four GFR-alpha  proteins share conserved placements of many of their cysteine residues. GFR alpha -1, 2, 3 or 4 have been shown to preferentially bind GDNF, NTN, ART and PSP, respectively. While the GFR alpha -3/Ret complex is highly specific for ART, the GFR alpha -1 /Ret complex is extremely promiscuous and may also be utilized by NTN and ART.

Human GFR alpha -3 cDNA encodes a 400 amino acid (aa) residue precursor protein with an N-terminal signal peptide and C-terminal hydrophobic domain. GFR alpha -3 is approximately 34% and 36% identical to GFR alpha -1 and GFR alpha -2, respectively. Human and mouse GFR alpha -3 share approximately 76% amino acid sequence homology. The gene encoding GFR alpha -3 has been localized to human chromosome 5. GFR alpha -3 is expressed at high levels only in the developing and adult sensory and sympathetic ganglia of the peripheral nervous system. In the trigeminal ganglions, the expression of GFR alpha -3 is found in a population of neurons distinct from those expressing GFR alpha -1 or 2.
