This allele, which encodes ERBB receptor feedback inhibitor 1 protein, is involved in the regulation of EGF receptor signaling.

(ERRFI1 wt Allele, NCI Thesaurus)

Upon administration of GTx-758, this agent suppresses the secretion of the gonadotropins follicle-stimulating hormone (FSH) and luteinizing hormone (LH) by the pituitary gland through feedback inhibition.
