GDNF family receptor alpha-4
Function
Receptor for persephin (PSPN), a growth factor that exhibits neurotrophic activity on mesencephalic dopaminergic and motor neurons (PubMed:11116144). Acts by binding to its coreceptor, GFRA4, leading to autophosphorylation and activation of the RET receptor (PubMed:11116144). May be important in C-cell development and, in the postnatal development of the adrenal medulla (PubMed:11116144).
Sequence Similarities
Belongs to the GDNFR family.

Predominantly expressed in the adult thyroid gland. Low levels also found in fetal adrenal and thyroid glands.
