NMR Structure(hide GO term definitions)
Chain A   (CAMP_HUMAN | P49913)
molecular function
    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:0019731    antibacterial humoral response    An immune response against bacteria mediated through a body fluid. Examples of this process are the antibacterial humoral responses in Mus musculus and Drosophila melanogaster.
    GO:0019732    antifungal humoral response    An immune response against a fungus mediated through a body fluid. An example of this process is the antifungal humoral response in Drosophila melanogaster.
    GO:0045454    cell redox homeostasis    Any process that maintains the redox environment of a cell or compartment within a cell.
    GO:0002544    chronic inflammatory response    Inflammation of prolonged duration (weeks or months) in which active inflammation, tissue destruction, and attempts at repair are proceeding simultaneously. Although it may follow acute inflammation, chronic inflammation frequently begins insidiously, as a low-grade, smoldering, often asymptomatic response.
    GO:0006952    defense response    Reactions, triggered in response to the presence of a foreign body or the occurrence of an injury, which result in restriction of damage to the organism attacked or prevention/recovery from the infection caused by the attack.
    GO:0050829    defense response to Gram-negative bacterium    Reactions triggered in response to the presence of a Gram-negative bacterium that act to protect the cell or organism.
    GO:0050830    defense response to Gram-positive bacterium    Reactions triggered in response to the presence of a Gram-positive bacterium that act to protect the cell or organism.
    GO:0042742    defense response to bacterium    Reactions triggered in response to the presence of a bacterium that act to protect the cell or organism.
    GO:0045087    innate immune response    Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
    GO:0002227    innate immune response in mucosa    Any process of the innate immune response that takes place in the mucosal tissues.
    GO:0051873    killing by host of symbiont cells    Any process mediated by an organism that results in the death of cells in the symbiont organism. The symbiont is defined as the smaller of the organisms involved in a symbiotic interaction.
    GO:0044140    negative regulation of growth of symbiont on or near host surface    Any process that stops, prevents, or reduces the frequency, rate or extent of the increase in the symbiont's size or mass on or near the cells or tissues of the host organism.
    GO:2000484    positive regulation of interleukin-8 secretion    Any process that activates or increases the frequency, rate or extent of interleukin-8 secretion.
    GO:0001878    response to yeast    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus from a yeast species.
cellular component
    GO:0005618    cell wall    The rigid or semi-rigid envelope lying outside the cell membrane of plant, fungal, most prokaryotic cells and some protozoan parasites, maintaining their shape and protecting them from osmotic lysis. In plants it is made of cellulose and, often, lignin; in fungi it is composed largely of polysaccharides; in bacteria it is composed of peptidoglycan; in protozoan parasites such as Giardia species, it's made of carbohydrates and proteins.
    GO:0070062    extracellular exosome    A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
    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.
    GO:0005622    intracellular    The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm.
    GO:0042581    specific granule    Granule with a membranous, tubular internal structure, found primarily in mature neutrophil cells. Most are released into the extracellular fluid. Specific granules contain lactoferrin, lysozyme, vitamin B12 binding protein and elastase.
