该基因编码1型促性腺激素释放激素受体该受体是七个跨膜g蛋白偶联受体（gpcr）家族的成员。它在垂体促性腺激素细胞以及淋巴细胞、乳腺、卵巢和前列腺的表面表达。在促性腺激素释放激素结合后，受体与激活磷脂酰肌醇钙第二信使系统的G蛋白结合。受体的激活最终导致促性腺激素黄体生成素（LH）和卵泡刺激素（FSH）的释放该基因的缺陷是导致低促性腺激素性性腺功能减退（hh）的原因之一。选择性剪接导致编码不同亚型的多个转录变体该基因在5'区有18个以上的转录起始位点，在3'区有多个polya信号。[由RefSeq提供，2008年7月]
This gene encodes the receptor for type 1 gonadotropin-releasing hormone. This receptor is a member of the seven-transmembrane, G-protein coupled receptor (GPCR) family. It is expressed on the surface of pituitary gonadotrope cells as well as lymphocytes, breast, ovary, and prostate. Following binding of gonadotropin-releasing hormone, the receptor associates with G-proteins that activate a phosphatidylinositol-calcium second messenger system. Activation of the receptor ultimately causes the release of gonadotropic luteinizing hormone (LH) and follicle stimulating hormone (FSH). Defects in this gene are a cause of hypogonadotropic hypogonadism (HH). Alternative splicing results in multiple transcript variants encoding different isoforms. More than 18 transcription initiation sites in the 5' region and multiple polyA signals in the 3' region have been identified for this gene. [provided by RefSeq, Jul 2008]
