GDNF and GFR alpha ‑1 in Rat Dorsal Root Ganglia. GDNF and GFRa-1 were detected in perfusion fixed frozen sections of rat dorsal root ganglia using 10 µg/mL Human/Rat GDNF Antigen Affinity-purified Polyclonal Antibody (green; Catalog # AF-212-NA) and 15 µg/mL Goat AntiRat Anti-GFRa-1 Biotinylated Antigen Affinity-purified Poly-clonal Antibody (red; Catalog # BAF560). Tissue was incubated with primary antibodies overnight at 4 °C. View our protocol for Fluorescent IHC Staining of Frozen Tissue Sections.

Background: GFR alpha-1/GDNF R alpha-1
Glial cell line-derived growth factor (GDNF), neurturin (NTN) and persephin, 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 GDNF and NTN are mediated through a receptor complex composed of the non ligand-binding signaling subunit (c-Ret receptor tyrosine kinase) and either of two ligand binding subunits (GDNF receptor alpha - (GFR alpha -1) or GFR alpha -2). GFR alpha -1 and -2 are members of a family of at least four cysteine-rich glycosyl-phosphatidylinositol (GPI)-linked cell surface proteins that share conserved placements of many of their cysteine residues. Binding of GDNF to membrane-associated GFR alpha -1 or GFR alpha -2 initiates the association with and activation of the Ret tyrosine kinase. Soluble GFR alpha s released enzymatically from the cell surface-associated protein with phosphatidylinositol phospholipase C, as well as recombinantly produced soluble GFR alpha -1, can also bind with high-affinity to GDNF and trigger the activation of Ret tyrosine kinase. Rat GFR alpha -1 cDNA encodes a 468 amino acid (aa) residue protein with an N‑terminal 24 aa residue hydrophobic signal peptide. Like other GPI-linked proteins, rat GFR alpha -1 has a C-terminal hydrophobic region which is preceded by a three aa residue (ASS) GPI-binding site. Human GFR alpha -1 shares 93% amino acid identity with rat GFR alpha -1. The expression of the various GFR alpha s are differentially regulated in the central and peripheral nervous system, suggesting complementary roles for the GFR alpha s in mediating the activities of the GDNF family of neurotrophic factors.
