Chain A,B   (CED9_CAEEL | P41958)
molecular function
    GO:0005096    GTPase activator activity    Binds to and increases the activity of a GTPase, an enzyme that catalyzes the hydrolysis of GTP.
    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:0046982    protein heterodimerization activity    Interacting selectively and non-covalently with a nonidentical protein to form a heterodimer.
    GO:0042803    protein homodimerization activity    Interacting selectively and non-covalently with an identical protein to form a homodimer.
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:1902742    apoptotic process involved in development    Any apoptotic process that is involved in anatomical structure development.
    GO:0000422    autophagy of mitochondrion    The autophagic process in which mitochondria are delivered to the vacuole and degraded in response to changing cellular conditions.
    GO:0097192    extrinsic apoptotic signaling pathway in absence of ligand    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 withdrawal of a ligand from a cell surface receptor, and ends when the execution phase of apoptosis is triggered.
    GO:0008630    intrinsic apoptotic signaling pathway in response to DNA damage    A series of molecular signals in which an intracellular signal is conveyed to trigger the apoptotic death of a cell. The pathway is induced by the detection of DNA damage, and ends when the execution phase of apoptosis is triggered.
    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:2001243    negative regulation of intrinsic apoptotic signaling pathway    Any process that stops, prevents or reduces the frequency, rate or extent of intrinsic apoptotic signaling pathway.
    GO:0043069    negative regulation of programmed cell death    Any process that stops, prevents, or reduces the frequency, rate or extent of programmed cell death, cell death resulting from activation of endogenous cellular processes.
    GO:0043547    positive regulation of GTPase activity    Any process that activates or increases the activity of a GTPase.
    GO:0010636    positive regulation of mitochondrial fusion    Any process that increases the frequency, rate or extent of merging of two or more mitochondria within a cell to form a single compartment.
    GO:0042981    regulation of apoptotic process    Any process that modulates the occurrence or rate of cell death by apoptotic process.
cellular component
    GO:0012505    endomembrane system    A collection of membranous structures involved in transport within the cell. The main components of the endomembrane system are endoplasmic reticulum, Golgi bodies, vesicles, cell membrane and nuclear envelope. Members of the endomembrane system pass materials through each other or though the use of vesicles.
    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:0031090    organelle membrane    A membrane that is one of the two lipid bilayers of an organelle envelope or the outermost membrane of single membrane bound organelle.
    GO:0048471    perinuclear region of cytoplasm    Cytoplasm situated near, or occurring around, the nucleus.
