NCIt definition : Progonadoliberin-1 (92 aa, 10 kDa) is encoded by the human GNRH1 gene. This protein
plays a role in regulating the secretion of both luteinizing and follicle-stimulating
hormones (LH and FSH, respectively).;
NCIt note : Progonadoliberin-1 is cleaved into 2 active peptides comprised of either amino acid
residues 24-33, which is called gonadoliberin-1 (gonadoliberin I; gonadorelin; gonadotropin-releasing
hormone I; GnRH-I; luliberin I; luteinizing hormone-releasing hormone I; LH-RH I;
prolactin release-inhibiting factor; PIF), or residues 37-92, which is called GnRH-associated
peptide 1 (GnRH-associated peptide I). (UniProt);
