NMR Structure(hide GO term definitions)
Chain A   (GON1_SHEEP | Q28588)
molecular function
    GO:0005183    gonadotropin hormone-releasing hormone activity    The action characteristic of gonadotropin hormone-releasing hormone (GnRH), any of a family of decapeptide amide hormones that are released by the hypothalamus in response to neural and/or chemical stimuli. In at least mammals, upon receptor binding, GnRH causes the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) by the anterior pituitary.
    GO:0005179    hormone activity    The action characteristic of a hormone, any substance formed in very small amounts in one specialized organ or group of cells and carried (sometimes in the bloodstream) to another organ or group of cells in the same organism, upon which it has a specific regulatory action. The term was originally applied to agents with a stimulatory physiological action in vertebrate animals (as opposed to a chalone, which has a depressant action). Usage is now extended to regulatory compounds in lower animals and plants, and to synthetic substances having comparable effects; all bind receptors and trigger some biological process.
biological process
    GO:0007275    multicellular organism development    The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult).
    GO:0046880    regulation of follicle-stimulating hormone secretion    Any process that modulates the frequency, rate or extent of the regulated release of follicle-stimulating hormone.
    GO:0033684    regulation of luteinizing hormone secretion    Any process that modulates the frequency, rate or extent of the regulated release of luteinizing hormone.
cellular component
    GO:0005576    extracellular region    The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
