Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B   (AIM2_HUMAN | O14862)
molecular function
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0003690    double-stranded DNA binding    Interacting selectively and non-covalently with double-stranded DNA.
    GO:0042802    identical protein binding    Interacting selectively and non-covalently with an identical protein or proteins.
    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:0002218    activation of innate immune response    Any process that initiates an innate immune response. Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens. Examples of this process include activation of the hypersensitive response of Arabidopsis thaliana and activation of any NOD or TLR signaling pathway in vertebrate species.
    GO:0006915    apoptotic process    A programmed cell death process which begins when a cell receives an internal (e.g. DNA damage) or external signal (e.g. an extracellular death ligand), and proceeds through a series of biochemical events (signaling pathway phase) which trigger an execution phase. The execution phase is the last step of an apoptotic process, and is typically characterized by rounding-up of the cell, retraction of pseudopodes, reduction of cellular volume (pyknosis), chromatin condensation, nuclear fragmentation (karyorrhexis), plasma membrane blebbing and fragmentation of the cell into apoptotic bodies. When the execution phase is completed, the cell has died.
    GO:0035690    cellular response to drug    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.
    GO:0035458    cellular response to interferon-beta    Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an interferon-beta stimulus. Interferon-beta is a type I interferon.
    GO:0006955    immune response    Any immune system process that functions in the calibrated response of an organism to a potential internal or invasive threat.
    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:0006954    inflammatory response    The immediate defensive reaction (by vertebrate tissue) to infection or injury caused by chemical or physical agents. The process is characterized by local vasodilation, extravasation of plasma into intercellular spaces and accumulation of white blood cells and macrophages.
    GO:0045087    innate immune response    Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.
    GO:0050702    interleukin-1 beta secretion    The regulated release of interleukin 1 beta from a cell.
    GO:0032088    negative regulation of NF-kappaB transcription factor activity    Any process that stops, prevents, or reduces the frequency, rate or extent of the activity of the transcription factor NF-kappaB.
    GO:0051092    positive regulation of NF-kappaB transcription factor activity    Any process that activates or increases the frequency, rate or extent of activity of the transcription factor NF-kappaB.
    GO:2001056    positive regulation of cysteine-type endopeptidase activity    Any process that activates or increases the frequency, rate or extent of cysteine-type endopeptidase activity.
    GO:0002230    positive regulation of defense response to virus by host    Any host process that results in the promotion of antiviral immune response mechanisms, thereby limiting viral replication.
    GO:0032731    positive regulation of interleukin-1 beta production    Any process that activates or increases the frequency, rate, or extent of interleukin-1 beta production.
    GO:0050718    positive regulation of interleukin-1 beta secretion    Any process that activates or increases the frequency, rate or extent of the regulated release of interleukin-1 beta from a cell.
    GO:0032461    positive regulation of protein oligomerization    Any process that activates or increases the frequency, rate or extent of protein oligomerization.
    GO:0070269    pyroptosis    A caspase-1-dependent cell death subroutine that is associated with the generation of pyrogenic mediators such as IL-1beta and IL-18.
    GO:0033209    tumor necrosis factor-mediated signaling pathway    A series of molecular signals initiated by the binding of a tumor necrosis factor to a receptor on the surface of a cell, and ending with regulation of a downstream cellular process, e.g. transcription.
cellular component
    GO:0097169    AIM2 inflammasome complex    A protein complex that consists of AIM2, ASC, and caspase-1. AIM2 is a member of the HN-200 protein family that appears to be the sensor of cytosolic double-stranded DNA.
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    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.
