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.
