RT   evolutionary implications.";
RL   Proc. Natl. Acad. Sci. U.S.A. 93:10461-10464(1996).
CC   -!- FUNCTION: Stimulates the secretion of gonadotropins; it stimulates the
CC       secretion of both luteinizing and follicle-stimulating hormones.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: GNRH neurons lie within blood sinuses close to the
CC       gonoducts and gonads in both juveniles and adults, implying that the
CC       neuropeptide is released into the bloodstream.
CC   -!- MASS SPECTROMETRY: Mass=1246.56; Method=MALDI;
CC       Evidence={ECO:0000269|PubMed:8816823};
CC   -!- SIMILARITY: Belongs to the GnRH family. {ECO:0000305}.
