| | GO:0048306 | | calcium-dependent 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), in the presence of calcium. |
| | 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:0005537 | | mannose binding | | Interacting selectively and non-covalently with mannose, a monosaccharide hexose, stereoisomeric with glucose, that occurs naturally only in polymerized forms called mannans. |
| | 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). |
| | GO:0005102 | | receptor binding | | Interacting selectively and non-covalently with one or more specific sites on a receptor molecule, a macromolecule that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function. |
| | GO:0004252 | | serine-type endopeptidase activity | | Catalysis of the hydrolysis of internal, alpha-peptide bonds in a polypeptide chain by a catalytic mechanism that involves a catalytic triad consisting of a serine nucleophile that is activated by a proton relay involving an acidic residue (e.g. aspartate or glutamate) and a basic residue (usually histidine). |
| 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:0006956 | | complement activation | | Any process involved in the activation of any of the steps of the complement cascade, which allows for the direct killing of microbes, the disposal of immune complexes, and the regulation of other immune processes; the initial steps of complement activation involve one of three pathways, the classical pathway, the alternative pathway, and the lectin pathway, all of which lead to the terminal complement pathway. |
| | GO:0006958 | | complement activation, classical pathway | | Any process involved in the activation of any of the steps of the classical pathway of the complement cascade which allows for the direct killing of microbes, the disposal of immune complexes, and the regulation of other immune processes. |
| | GO:0001867 | | complement activation, lectin pathway | | Any process involved in the activation of any of the steps of the lectin pathway of the complement cascade which allows for the direct killing of microbes and the regulation of other immune processes. |
| | 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:0002376 | | immune system process | | Any process involved in the development or functioning of the immune system, an organismal system for calibrated responses to potential internal or invasive threats. |
| | GO:0045087 | | innate immune response | | Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. |
| | 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:0044130 | | negative regulation of growth of symbiont in host | | Any process in which the symbiont stops, prevents or reduces its increase in size or mass within the cells or tissues of the host organism. The host is defined as the larger of the organisms involved in the symbiotic interaction. |
| | 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:0008228 | | opsonization | | The process in which a microorganism (or other particulate material) is rendered more susceptible to phagocytosis by coating with an opsonin, a blood serum protein such as a complement component or antibody. |
| | GO:0050766 | | positive regulation of phagocytosis | | Any process that activates or increases the frequency, rate or extent of phagocytosis. |
| | GO:0006508 | | proteolysis | | The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds. |
| | GO:0006979 | | response to oxidative stress | | 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 oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, e.g. superoxide anions, hydrogen peroxide (H2O2), and hydroxyl radicals. |
| cellular component |
|---|
| | GO:0009986 | | cell surface | | The external part of the cell wall and/or plasma membrane. |
| | GO:0005581 | | collagen trimer | | A protein complex consisting of three collagen chains assembled into a left-handed triple helix. These trimers typically assemble into higher order structures. |
| | 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. |
