High Profile Papers Identify GFRAL as a GDF-15 Receptor and Novel Target for Obesity and Anorexia/Cachexia

Wednesday, January 10, 2018 - 10:16

Growth Differentiation Factor 15 (GDF-15) has long been recognized as a circulating biomarker for a range of human disorders, and elevated levels have been associated with suppression of appetite. The receptor for this affect was recently revealed in several publications to be GDNF receptor-alpha-like (GFRAL), a distant member of the GDNF R family of proteins (1-4). The full receptor complex is composed of both Ret tyrosine kinase and GFRAL dimers. This newly discovered role for GFRAL places it in a position to act as a drug target for appetite regulation and obesity. This is an exciting finding given the great impact obesity-related disorders have on economic and social well-being. GFRAL could also be targeted to treat suppressed appetite often associated with chronic disease.

R&D Systems is pleased to offer purified Recombinant Human GFRAL with both His and Fc tags to assist in studies designed to gain a further understanding of GFRAL activity. These new proteins bind to Recombinant GDF-15 in the pg/mL range.
