GFRalpha3 is an orphan member of the GDNF/neurturin/persephin receptor family.

ABSTRACT: GDNF, neurturin, and persephin are transforming growth factor beta-related neurotrophic factors known collectively as the GDNF family (GF). GDNF and neurturin signal through a multicomponent receptor complex containing a signaling component (the Ret receptor tyrosine kinase) and either of two glycosyl-phosphatidylinositol-linked binding components (GDNF family receptor alpha components 1 and 2, GFRalpha1 or GFRalpha2), whereas the receptor for persephin is unknown. Herein we describe a third member of the GF coreceptor family called GFRalpha3 that is encoded by a gene located on human chromosome 5q31.2-32. GFRalpha3 is not expressed in the central nervous system of the developing or adult animal but is highly expressed in several developing and adult sensory and sympathetic ganglia of the
