Phospho-Ret (Tyr905) Antibody detects endogenous levels of Ret only when phosphorylated at tyrosine 905.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr905 of human Ret. Antibodies are purified by protein A and peptide affinity chromatography.
Background
The Ret proto-oncogene (c-Ret) is a receptor tyrosine kinase that functions as a multicompetent receptor complex in conjunction with other membrane-bound ligand-binding GDNF family receptors (1). Ligands that bind the Ret receptor include the glial cell line-derived neurotropic factor (GDNF) and its congeners neurturin, persephin and artemin (2-4). Alterations in the corresponding Ret gene are associated with diseases including papillary thyroid carcinoma, multiple endocrine neoplasia (type 2A and 2B), familial medullary thyroid carcinoma and a congenital developmental disorder known as Hirschsprung’s disease (1,3). The Tyr905 residue located in the Ret kinase domain plays a crucial role in Ret catalytic and biological activity. Substitution of Phe for Tyr905 dramatically inhibits Ret autophosphorylation activity (5).
