NMR Structure(hide GO term definitions)
Chain A   (PYY_PIG | P68005)
molecular function
    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:0031841    neuropeptide Y receptor binding    Interacting selectively and non-covalently with a neuropeptide Y receptor.
    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.
biological process
    GO:0007267    cell-cell signaling    Any process that mediates the transfer of information from one cell to another. This process includes signal transduction in the receiving cell and, where applicable, release of a ligand and any processes that actively facilitate its transport and presentation to the receiving cell. Examples include signaling via soluble ligands, via cell adhesion molecules and via gap junctions.
    GO:0007586    digestion    The whole of the physical, chemical, and biochemical processes carried out by multicellular organisms to break down ingested nutrients into components that may be easily absorbed and directed into metabolism.
    GO:0007631    feeding behavior    Behavior associated with the intake of food.
    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:0032098    regulation of appetite    Any process which modulates appetite, the desire or physical craving for food.
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.
    GO:0005615    extracellular space    That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.
