Chain A   (UCN1_HUMAN | P55089)
molecular function
    GO:0001664    G-protein coupled receptor binding    Interacting selectively and non-covalently with a G-protein coupled receptor.
    GO:0051430    corticotropin-releasing hormone receptor 1 binding    Interacting selectively and non-covalently with the corticotropin-releasing hormone receptor 1 (CRHR1). CRHR1 is the major subtype in the pituitary corticotroph, and mediates the stimulatory actions of corticotropin-releasing hormone on corticotropin hormone secretion. CRHR1 are also located in cortical areas of the brain, cerebellum and limbic system.
    GO:0051431    corticotropin-releasing hormone receptor 2 binding    Interacting selectively and non-covalently with the corticotropin-releasing hormone receptor type 2 (CRHR2). The CRHR2 has several splice variants that are located in sub-cortical areas of the brain and in the periphery.
    GO:0046811    histone deacetylase inhibitor activity    Stops, prevents or reduces the activity of histone deacetylase, which catalyzes of the removal of acetyl groups from histones, proteins complexed to DNA in chromatin and chromosomes.
    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.
    GO:0005184    neuropeptide hormone activity    The action characteristic of a neuropeptide hormone, any peptide hormone that acts in the central nervous system. A neuropeptide is any of several types of molecules found in brain tissue, composed of short chains of amino acids; they include endorphins, enkephalins, vasopressin, and others. They are often localized in axon terminals at synapses and are classified as putative neurotransmitters, although some are also hormones.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
biological process
    GO:0007186    G-protein coupled receptor signaling pathway    A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription. The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576).
    GO:0034199    activation of protein kinase A activity    Any process that initiates the activity of the inactive enzyme protein kinase A.
    GO:0009060    aerobic respiration    The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which requires oxygen as the terminal electron acceptor.
    GO:0008306    associative learning    Learning by associating a stimulus (the cause) with a particular outcome (the effect).
    GO:0042756    drinking behavior    The specific behavior of an organism relating to the intake of liquids, especially water.
    GO:0007631    feeding behavior    Behavior associated with the intake of food.
    GO:0007565    female pregnancy    The set of physiological processes that allow an embryo or foetus to develop within the body of a female animal. It covers the time from fertilization of a female ovum by a male spermatozoon until birth.
    GO:0035483    gastric emptying    The process in which the liquid and liquid-suspended solid contents of the stomach exit through the pylorus into the duodenum.
    GO:0006954    inflammatory response    The immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents. The process is characterized by local vasodilation, extravasation of plasma into intercellular spaces and accumulation of white blood cells and macrophages.
    GO:0007611    learning or memory    The acquisition and processing of information and/or the storage and retrieval of this information over time.
    GO:0043066    negative regulation of apoptotic process    Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.
    GO:0032099    negative regulation of appetite    Any process that reduces appetite.
    GO:0045776    negative regulation of blood pressure    Any process in which the force of blood traveling through the circulatory system is decreased.
    GO:0060548    negative regulation of cell death    Any process that decreases the rate or frequency of cell death. Cell death is the specific activation or halting of processes within a cell so that its vital functions markedly cease, rather than simply deteriorating gradually over time, which culminates in cell death.
    GO:0045792    negative regulation of cell size    Any process that reduces cell size.
    GO:2000252    negative regulation of feeding behavior    Any process that stops, prevents or reduces the frequency, rate or extent of feeding behavior.

    GO:0010629    negative regulation of gene expression    Any process that decreases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
    GO:0031064    negative regulation of histone deacetylation    Any process that stops, prevents, or reduces the frequency, rate or extent of the removal of acetyl groups from histones.
    GO:0046888    negative regulation of hormone secretion    Any process that stops, prevents, or reduces the frequency, rate or extent of the regulated release of a hormone from a cell.
    GO:0060547    negative regulation of necrotic cell death    Any process that decreases the rate, frequency or extent of necrotic cell death.

    GO:1901215    negative regulation of neuron death    Any process that stops, prevents or reduces the frequency, rate or extent of neuron death.
    GO:0031175    neuron projection development    The process whose specific outcome is the progression of a neuron projection over time, from its formation to the mature structure. A neuron projection is any process extending from a neural cell, such as axons or dendrites (collectively called neurites).
    GO:0007218    neuropeptide signaling pathway    The series of molecular signals generated as a consequence of a peptide neurotransmitter binding to a cell surface receptor.
    GO:0030157    pancreatic juice secretion    The regulated release of pancreatic juice by the exocrine pancreas into the upper part of the intestine. Pancreatic juice is slightly alkaline and contains numerous enzymes and inactive enzyme precursors including alpha-amylase, chymotrypsinogen, lipase, procarboxypeptidase, proelastase, prophospholipase A2, ribonuclease, and trypsinogen. Its high concentration of bicarbonate ions helps to neutralize the acid from the stomach.
