Chain A,B,C,D,E   (SAMP_HUMAN | P02743)
molecular function
    GO:0005509    calcium ion binding    Interacting selectively and non-covalently with calcium ions (Ca2+).
    GO:0030246    carbohydrate binding    Interacting selectively and non-covalently with any carbohydrate, which includes monosaccharides, oligosaccharides and polysaccharides as well as substances derived from monosaccharides by reduction of the carbonyl group (alditols), by oxidation of one or more hydroxy groups to afford the corresponding aldehydes, ketones, or carboxylic acids, or by replacement of one or more hydroxy group(s) by a hydrogen atom. Cyclitols are generally not regarded as carbohydrates.
    GO:0001849    complement component C1q binding    Interacting selectively and non-covalently with the C1q component of the classical complement cascade.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0051082    unfolded protein binding    Interacting selectively and non-covalently with an unfolded protein.
    GO:0046790    virion binding    Interacting selectively and non-covalently with a virion, either by binding to components of the capsid or the viral envelope.
biological process
    GO:0006953    acute-phase response    An acute inflammatory response that involves non-antibody proteins whose concentrations in the plasma increase in response to infection or injury of homeothermic animals.
    GO:0044267    cellular protein metabolic process    The chemical reactions and pathways involving a specific protein, rather than of proteins in general, occurring at the level of an individual cell. Includes cellular protein modification.
    GO:0051131    chaperone-mediated protein complex assembly    The aggregation, arrangement and bonding together of a set of components to form a protein complex, mediated by chaperone molecules that do not form part of the finished complex.
    GO:0045087    innate immune response    Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
    GO:0044869    negative regulation by host of viral exo-alpha-sialidase activity    The process in which a host organism decreases viral exo-alpha-sialidase activity, the catalysis of the hydrolysis of peptide bonds in a protein.
    GO:0044871    negative regulation by host of viral glycoprotein metabolic process    A process in which a host organism stops, prevents or reduces the frequency, rate or extent of viral glycoprotein metabolic process.
    GO:0002674    negative regulation of acute inflammatory response    Any process that stops, prevents, or reduces the frequency, rate, or extent of an acute inflammatory response.
    GO:1903016    negative regulation of exo-alpha-sialidase activity    Any process that stops, prevents or reduces the frequency, rate or extent of exo-alpha-sialidase activity.
    GO:1903019    negative regulation of glycoprotein metabolic process    Any process that stops, prevents or reduces the frequency, rate or extent of glycoprotein metabolic process.
    GO:0045656    negative regulation of monocyte differentiation    Any process that stops, prevents, or reduces the frequency, rate or extent of monocyte differentiation.
    GO:0046597    negative regulation of viral entry into host cell    Any process that stops, prevents, or reduces the frequency, rate or extent of the entry of viral entry into a host cell.
    GO:0048525    negative regulation of viral process    Any process that stops, prevents, or reduces the frequency, rate or extent of a multi-organism process in which a virus is a participant.
    GO:0061045    negative regulation of wound healing    Any process that decreases the rate, frequency, or extent of the series of events that restore integrity to a damaged tissue, following an injury.
    GO:0006457    protein folding    The process of assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure.
cellular component
    GO:0072562    blood microparticle    A phospholipid microvesicle that is derived from any of several cell types, such as platelets, blood cells, endothelial cells, or others, and contains membrane receptors as well as other proteins characteristic of the parental cell. Microparticles are heterogeneous in size, and are characterized as microvesicles free of nucleic acids.
    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:0031012    extracellular matrix    A structure lying external to one or more cells, which provides structural support for cells or tissues.
    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:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
