NCIt definition : Gonadotropin-releasing hormone receptor (328 aa, 38 kDa) is encoded by the human
GNRHR gene. This protein is involved in the regulation of pituitary hormone release
and G protein-coupled receptor signaling.;
NCIt note : Expressed as 2 alternative isoforms in pituitary, ovary, testis, breast, and prostate
by human GNRHR Gene (GPCR1 Family), Gonadotropin-Releasing Hormone Receptor is a cell
surface G protein-coupled 7-transmembrane-domain receptor that transduces signals
from hypothalamic decapeptide GNRH by association with G proteins that activate a
calcium-phosphatidylinositol second messenger system. A neuroregulator of reproduction,
the primary site of GNRH action is pituitary gonadotropes, which express GNRH receptors
that modulate synthesis and secretion of gonadotropic hormones LH and FSH, which regulate
gametogenic and hormonal functions of gonads. GNRHR Isoform 2 may act as an inhibitor
of GNRHR signaling.;
