Gonadotropin releasing hormone 1 receptor

spinqualitylabelsall models Caption for this structure Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D It is a member of the seven-transmembrane, G-protein coupled receptor (GPCR) family and is activated by the peptide hormone gonadotropin-releasing hormone (GnRH) or the synthetic agonist. The GnRHR is expressed on the surface of pituitary gonadotrope cells as well as lymphocytes, breast, ovary, and prostate. Its activity is critical for successful reproductive function. Several diseases are associated with a dysfunction of this receptor or the corresponding signaling cascade. You may include any references to papers as in: the use of JSmol in Proteopedia or to the article describing Jmol to the rescue. Biological Function The gonadotropin releasing hormone 1 receptor is activated by GnRH which acts upon GnRHRs as the key regulator of puberty and reproduction. This peptide hormone is produced in the hypothalamus but gets secreted and acts upon GnRHRs in the anterior pituitary to exert its effects on reproductive maturation. The activation of the receptor, associates with G-proteins, leads to the releasing of gonadotropic luteinizing hormone (LH) and follicle stimulating hormone (FSH) by activating several signaling cascades. These pathways mainly corresponds to the inositol 1,4,5-triphosphate (IP3) and diacylglycerol (DAG), MAPK, and adenyl cyclase pathways. Disease A mutation or a dysfonctionnement of the receptor could cause disease like idiopatic hypogonadotropic hypogonadism (HH) which is a disease causing hypogonadism. . Relevance One of the main using of the couple GnRH - GnRHR in the medicine field is for fertility preservation . Structural highlights This is a sample scene created with SAT to color by Group, and another to make a transparent representation of the protein. You can make your own scenes on SAT starting from scratch or loading and editing one of these sample scenes.
