Background

GFR alpha-like (GDNF receptor-alpha-like) is a 25 kDa dimer and distant member of the GDNFR family of proteins (1). It is expressed on both fetal and adult hindbrain neurons of the CNS (2), and would appear to function as an anti-apoptotic molecule during neuronal stress. GFR alpha-like is a funcation receptor of GDF15 and implicated in diet-based obesity and insulin resistance through c-Ret signaling (2 - 4). Mature mouse GFR alpha-like is a 374 amino acid (aa) type I transmembrane protein. It contains a 330 aa extracellular region that shows a Gas1 domain (aa 220‑316), and a 23 aa cytoplasmic tail. Over aa 19‑353, mouse GFR alpha-like shares 72% and 71% aa identity with human and rat GFR alpha–like, respectively.
