Chain A   (BIRC2_HUMAN | Q13490)
molecular function
    GO:0043027    cysteine-type endopeptidase inhibitor activity involved in apoptotic process    Stops, prevents or reduces the activity of a cysteine-type endopeptidase involved in the apoptotic process.
    GO:0016874    ligase activity    Catalysis of the joining of two substances, or two groups within a single molecule, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0047485    protein N-terminus binding    Interacting selectively and non-covalently with a protein N-terminus, the end of any peptide chain at which the 2-amino (or 2-imino) function of a constituent amino acid is not attached in peptide linkage to another amino-acid residue.
    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:0003713    transcription coactivator activity    Interacting selectively and non-covalently with a activating transcription factor and also with the basal transcription machinery in order to increase the frequency, rate or extent of transcription. Cofactors generally do not bind the template nucleic acid, but rather mediate protein-protein interactions between activating transcription factors and the basal transcription machinery.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
    GO:0004842    ubiquitin-protein transferase activity    Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y --> Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0007249    I-kappaB kinase/NF-kappaB signaling    The process in which a signal is passed on to downstream components within the cell through the I-kappaB-kinase (IKK)-dependent activation of NF-kappaB. The cascade begins with activation of a trimeric IKK complex (consisting of catalytic kinase subunits IKKalpha and/or IKKbeta, and the regulatory scaffold protein NEMO) and ends with the regulation of transcription of target genes by NF-kappaB. In a resting state, NF-kappaB dimers are bound to I-kappaB proteins, sequestering NF-kappaB in the cytoplasm. Phosphorylation of I-kappaB targets I-kappaB for ubiquitination and proteasomal degradation, thus releasing the NF-kappaB dimers, which can translocate to the nucleus to bind DNA and regulate transcription.
    GO:0038061    NIK/NF-kappaB signaling    The process in which a signal is passed on to downstream components within the cell through the NIK-dependent processing and activation of NF-KappaB. Begins with activation of the NF-KappaB-inducing kinase (NIK), which in turn phosphorylates and activates IkappaB kinase alpha (IKKalpha). IKKalpha phosphorylates the NF-Kappa B2 protein (p100) leading to p100 processing and release of an active NF-KappaB (p52).
    GO:0035666    TRIF-dependent toll-like receptor signaling pathway    Any series of molecular signals generated as a consequence of binding to a toll-like receptor where the TRIF adaptor mediates transduction of the signal. Toll-like receptors directly bind pattern motifs from a variety of microbial sources to initiate innate immune response.
    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:0007166    cell surface receptor signaling pathway    A series of molecular signals initiated by activation of a receptor on the surface of a cell. The pathway begins with binding of an extracellular ligand to a cell surface receptor, or for receptors that signal in the absence of a ligand, by ligand-withdrawal or the activity of a constitutively active receptor. The pathway ends with regulation of a downstream cellular process, e.g. transcription.
    GO:0006921    cellular component disassembly involved in execution phase of apoptosis    The breakdown of structures such as organelles, proteins, or other macromolecular structures during apoptosis.
    GO:1990001    inhibition of cysteine-type endopeptidase activity involved in apoptotic process    Any process that prevents the activation of an inactive cysteine-type endopeptidase involved in an apoptotic process.
    GO:0090307    mitotic spindle assembly    The aggregation, arrangement and bonding together of a set of components to form the spindle that contributes to the process of mitosis.
    GO:0070266    necroptotic process    A programmed necrotic cell death process which begins when a cell receives a signal (e.g. a ligand binding to a death receptor or to a Toll-like receptor), and proceeds through a series of biochemical events (signaling pathways), characterized by activation of receptor-interacting serine/threonine-protein kinase 1 and/or 3 (RIPK1/3, also called RIP1/3) and by critical dependence on mixed lineage kinase domain-like (MLKL), and which typically lead to common morphological features of necrotic cell death. The process ends when the cell has died. The process is divided into a signaling phase, and an execution phase, which is triggered by the former.
    GO:0043066    negative regulation of apoptotic process    Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.
    GO:0060546    negative regulation of necroptotic process    Any process that decreases the rate, frequency or extent of a necroptotic process, a necrotic cell death process that results from the activation of endogenous cellular processes, such as signaling involving death domain receptors or Toll-like receptors.
    GO:1902443    negative regulation of ripoptosome assembly involved in necroptotic process    Any process that stops, prevents or reduces the frequency, rate or extent of ripoptosome assembly involved in a necroptotic process.
    GO:0001890    placenta development    The process whose specific outcome is the progression of the placenta over time, from its formation to the mature structure. The placenta is an organ of metabolic interchange between fetus and mother, partly of embryonic origin and partly of maternal origin.
    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:1902524    positive regulation of protein K48-linked ubiquitination    Any process that activates or increases the frequency, rate or extent of protein K48-linked ubiquitination.
    GO:1902523    positive regulation of protein K63-linked ubiquitination    Any process that activates or increases the frequency, rate or extent of protein K63-linked ubiquitination.
    GO:1902527    positive regulation of protein monoubiquitination    Any process that activates or increases the frequency, rate or extent of protein monoubiquitination.
    GO:0043161    proteasome-mediated ubiquitin-dependent protein catabolic process    The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome.
    GO:0051291    protein heterooligomerization    The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of component monomers that are not all identical. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.
    GO:0000209    protein polyubiquitination    Addition of multiple ubiquitin groups to a protein, forming a ubiquitin chain.
    GO:0039535    regulation of RIG-I signaling pathway    Any process that modulates the frequency, rate or extent of the 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.
