Asymmetric Unit(hide GO term definitions)
Chain A   (MAVS_HUMAN | Q7Z434)
molecular function
    GO:0050700    CARD domain binding    Interacting selectively and non-covalently with a CARD (N-terminal caspase recruitment) domain, a protein-protein interaction domain that belongs to the death domain-fold superfamily. These protein molecule families are similar in structure with each consisting of six or seven anti-parallel alpha-helices that form highly specific homophilic interactions between signaling partners. CARD exists in the N-terminal prodomains of several caspases and in apoptosis-regulatory proteins and mediates the assembly of CARD-containing proteins that participate in activation or suppression of CARD carrying members of the caspase family.
    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:0019901    protein kinase binding    Interacting selectively and non-covalently with a protein kinase, any enzyme that catalyzes the transfer of a phosphate group, usually from ATP, to a protein substrate.
    GO:0004871    signal transducer activity    Conveys a signal across a cell to trigger a change in cell function or state. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response.
biological process
    GO:0039529    RIG-I signaling pathway    Any series of molecular signals generated as a consequence of the cytoplasmic pattern recognition receptor (PRR) RIG-1 (also known as DDX58) binding to viral RNA. RIG-I detects RNA synthesized during active viral replication and triggers a signaling pathway to protect the host against viral infection, for example by inducing the expression of antiviral cytokines.
    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:0071360    cellular response to exogenous dsRNA    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 exogenous double-stranded RNA stimulus.
    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:0051607    defense response to virus    Reactions triggered in response to the presence of a virus 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:0032480    negative regulation of type I interferon production    Any process that stops, prevents, or reduces the frequency, rate, or extent of type I interferon production. Type I interferons include the interferon-alpha, beta, delta, episilon, zeta, kappa, tau, and omega gene families.
    GO:0045071    negative regulation of viral genome replication    Any process that stops, prevents, or reduces the frequency, rate or extent of viral genome replication.
    GO:0043123    positive regulation of I-kappaB kinase/NF-kappaB signaling    Any process that activates or increases the frequency, rate or extent of I-kappaB kinase/NF-kappaB signaling.
    GO:0071660    positive regulation of IP-10 production    Any process that activates or increases the frequency, rate, or extent of production of IP-10.
    GO:0071651    positive regulation of chemokine (C-C motif) ligand 5 production    Any process that activates or increases the frequency, rate, or extent of production of chemokine (C-C motif) ligand 5.
    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:0032727    positive regulation of interferon-alpha production    Any process that activates or increases the frequency, rate, or extent of interferon-alpha production.
    GO:0032728    positive regulation of interferon-beta production    Any process that activates or increases the frequency, rate, or extent of interferon-beta production.
    GO:0032757    positive regulation of interleukin-8 production    Any process that activates or increases the frequency, rate, or extent of interleukin-8 production.
    GO:0033160    positive regulation of protein import into nucleus, translocation    Any process that activates or increases the vectorial transfer of a protein from the cytoplasm into the nucleus, across the nuclear membrane.
    GO:0001934    positive regulation of protein phosphorylation    Any process that activates or increases the frequency, rate or extent of addition of phosphate groups to amino acids within a protein.
    GO:0051091    positive regulation of sequence-specific DNA binding transcription factor activity    Any process that activates or increases the frequency, rate or extent of activity of a transcription factor, any factor involved in the initiation or regulation of transcription.
    GO:0042993    positive regulation of transcription factor import into nucleus    Any process that activates or increases the frequency, rate or extent of the movement of a transcription factor from the cytoplasm to the nucleus.
    GO:0045944    positive regulation of transcription from RNA polymerase II promoter    Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0032760    positive regulation of tumor necrosis factor production    Any process that activates or increases the frequency, rate, or extent of tumor necrosis factor production.
    GO:0032481    positive regulation of type I interferon production    Any process that activates or increases the frequency, rate, or extent of type I interferon production. Type I interferons include the interferon-alpha, beta, delta, episilon, zeta, kappa, tau, and omega gene families.
    GO:0060340    positive regulation of type I interferon-mediated signaling pathway    Any process that increases the rate, frequency or extent of a type I interferon-mediated signaling pathway. A type I interferon-mediated signaling pathway is the series of molecular events generated as a consequence of a type I interferon binding to a cell surface receptor.
    GO:1900063    regulation of peroxisome organization    Any process that modulates the frequency, rate or extent of peroxisome organization.
    GO:0007165    signal transduction    The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.
    GO:0016032    viral process    A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.
cellular component
    GO:0016021    integral component of membrane    The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.
    GO:0016020    membrane    A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
    GO:0031966    mitochondrial membrane    Either of the lipid bilayers that surround the mitochondrion and form the mitochondrial envelope.
    GO:0005741    mitochondrial outer membrane    The outer, i.e. cytoplasm-facing, lipid bilayer of the mitochondrial envelope.
    GO:0005739    mitochondrion    A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
    GO:0005778    peroxisomal membrane    The lipid bilayer surrounding a peroxisome.
    GO:0005777    peroxisome    A small organelle enclosed by a single membrane, and found in most eukaryotic cells. Contains peroxidases and other enzymes involved in a variety of metabolic processes including free radical detoxification, lipid catabolism and biosynthesis, and hydrogen peroxide metabolism.
