Asymmetric Unit(hide GO term definitions)
Chain A,B,C,D,E,F   (BIRC8_HUMAN | Q96P09)
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:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    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: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: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:0090263    positive regulation of canonical Wnt signaling pathway    Any process that increases the rate, frequency, or extent of the Wnt signaling pathway through beta-catenin, the series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via beta-catenin, and ending with a change in transcription of target genes.
    GO:0016567    protein ubiquitination    The process in which one or more ubiquitin groups are added to a protein.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    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.
    GO:0005876    spindle microtubule    Any microtubule that is part of a mitotic or meiotic spindle; anchored at one spindle pole.

Chain G,H,I,J,K,L   (DBLOH_HUMAN | Q9NR28)
molecular function
    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:0006919    activation of cysteine-type endopeptidase activity involved in apoptotic process    Any process that initiates the activity of the inactive enzyme cysteine-type endopeptidase in the context of an apoptotic process.
    GO:0008635    activation of cysteine-type endopeptidase activity involved in apoptotic process by cytochrome c    Any process that initiates the activity of the inactive enzyme cysteine-type endopeptidase in the context of an apoptotic process and is mediated by cytochrome c.
    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:0008625    extrinsic apoptotic signaling pathway via death domain receptors    A series of molecular signals in which a signal is conveyed from the cell surface to trigger the apoptotic death of a cell. The pathway starts with a ligand binding to a death domain receptor on the cell surface, and ends when the execution phase of apoptosis is triggered.
    GO:0097193    intrinsic apoptotic signaling pathway    A series of molecular signals in which an intracellular signal is conveyed to trigger the apoptotic death of a cell. The pathway starts with reception of an intracellular signal (e.g. DNA damage, endoplasmic reticulum stress, oxidative stress etc.), and ends when the execution phase of apoptosis is triggered. The intrinsic apoptotic signaling pathway is crucially regulated by permeabilization of the mitochondrial outer membrane (MOMP).
    GO:0008631    intrinsic apoptotic signaling pathway in response to oxidative stress    A series of molecular signals in which an intracellular signal is conveyed to trigger the apoptotic death of a cell. The pathway is induced in response to oxidative stress, a state often resulting from exposure to high levels of reactive oxygen species, and ends when the execution phase of apoptosis is triggered.
    GO:0051402    neuron apoptotic process    Any apoptotic process in a neuron, the basic cellular unit of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the nervous system.
    GO:0043065    positive regulation of apoptotic process    Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process.
cellular component
    GO:0035631    CD40 receptor complex    A protein complex that contains at least CD40 (a cell surface receptor of the tumour necrosis factor receptor (TNFR) superfamily), and other signaling molecules.
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0009898    cytoplasmic side of plasma membrane    The leaflet the plasma membrane that faces the cytoplasm and any proteins embedded or anchored in it or attached to its surface.
    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:0005758    mitochondrial intermembrane space    The region between the inner and outer lipid bilayers 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.
