Stimulates the secretion of gonadotropins; it stimulates the secretion of both luteinizing and follicle-stimulating hormones. The precursor is cleaved by ACE, which removes the Gly-Lys-Arg peptide at the C-terminus, leading to mature hormone (PubMed:10336644, PubMed:7683654). The mature form of Gonadoliberin-1 is also cleaved and degraded by ACE (PubMed:2983326, PubMed:7683654). The disease is caused by variants affecting distinct genetic loci, including the gene represented in this entry. The genetics of hypogonadotropic hypogonadism involves various modes of transmission. Oligogenic inheritance has been reported in some patients carrying mutations in GNRH1 as well as in other HH-associated genes including PROKR2 and FGFR1 (PubMed:23643382). Available under the names Factrel (Ayerst Labs), Lutrepulse or Lutrelef (Ferring Pharmaceuticals) and Relisorm (Serono). Used in evaluating hypothalamic-pituitary gonadotropic function. The 3D-structure was determined for the synthetic analog Triptorelin. Belongs to the GnRH family. Gonadotropin-releasing hormone entry
