RET transforming sequence
The GDNF family of neurotrophic factors consititute a new family of factors within the TGF-beta superfamily. These proteins are potent survival factors for various central and peripheral neurons during development and in the adult animal. The GDNF family members (GDNF, neurturin and persephin) signal through multicomponent receptors that consist of the Ret receptor tyrosine kinase and one of four glycosyl-phosphatidylinositol (GPI)-linked ligand-binding subunits (GFR alpha ‑1 ‑ 4). GFR alpha -1, -2, and -4 are the preferred ligand-binding subunits for GDNF, neurturin and persephin, respectively. To date, the preferred ligand for GFR alpha ‑3 has not been identified. The Ret tyrosine-kinase receptor is encoded by the c-ret proto-oncogene. Mutations of the ret gene have been associated with various human diseases affecting tissues derived from the neural crest, including Hirschsprung’s disease, multiple endocrine neoplasia MEN2A and MEN2B, and familial medullary thyroid carcinoma. Mouse Ret cDNA encodes a 1115 amino acid (aa) residue transmembrane tyrosine kinase with a 28 aa residue signal peptide, a 609 aa residue cysteine-rich extracellular domain and a 456 aa residue cytoplasmic domain. A cadherin-related sequence is also present in the extracellular domain of Ret. Human and mouse Ret share 83% amino acid sequence homology (77% homology in the extracellular domain and 93% homology in the cytoplasmic domain). Although Ret does not bind GDNF ligands directly, the extracellular domain of Ret binds the GDNF-GFR-alpha complex with high affinity and is a potent GDNF antagonist in the presence of soluble GFR-alpha.
