    GO ID   Ontology GO Term Definition
    6914   Autophagy  The Process in Which Cells Digest Parts of Their Own Cytoplasm; Allows For Both Recycling of Macromolecular Constituents Under Conditions of Cellular Stress and Remodeling the Intracellular Structure For Cell Differentiation. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    Chain B,C
    GO ID   Ontology GO Term Definition
    45   Autophagic Vacuole Assembly  The Formation of a Double Membrane Bounded Structure the Autophagosome That Occurs When a Specialized Membrane Sac Called the Isolation Membrane Starts to Enclose a Portion of the Cytoplasm. 
    422   Mitochondrion Degradation  The Autophagic Process in Which Mitochondria Are Delivered to the Vacuole and Degraded in Response to Changing Cellular Conditions. 
    902   Cell Morphogenesis  The Developmental Process in Which the Size or Shape of a Cell Is Generated and Organized. 
    6623   Protein Targeting to Vacuole  The Process of Directing Proteins Towards the Vacuole Usually Using Signals Contained Within the Protein. 
    6810   Transport  The Directed Movement of Substances (such As Macromolecules Small Molecules Ions) Into Out of or Within a Cell or Between Cells or Within a Multicellular Organism by Means of Some Agent Such As a Transporter or Pore. 
    6914   Autophagy  The Process in Which Cells Digest Parts of Their Own Cytoplasm; Allows For Both Recycling of Macromolecular Constituents Under Conditions of Cellular Stress and Remodeling the Intracellular Structure For Cell Differentiation. 
    15031   Protein Transport  The Directed Movement of Proteins Into Out of or Within a Cell or Between Cells by Means of Some Agent Such As a Transporter or Pore. 
    16049   Cell Growth  The Process in Which a Cell Irreversibly Increases in Size Over Time by Accretion and Biosynthetic Production of Matter Similar to That Already Present. 
    16192   Vesicle Mediated Transport  A Cellular Transport Process in Which Transported Substances Are Moved in Membrane Bounded Vesicles; Transported Substances Are Enclosed in the Vesicle Lumen or Located in the Vesicle Membrane. the Process Begins with a Step That Directs a Substance to the Forming Vesicle and Includes Vesicle Budding and Coating. Vesicles Are Then Targeted to and Fuse with an Acceptor Membrane. 
    44804   Nucleophagy  A Selective Form of Autophagy by Which Damaged or Non Essential Parts of the Nucleus or Even an Entire Nucleus Is Degraded. 
    48193   Golgi Vesicle Transport  The Directed Movement of Substances Into Out of or Within the Golgi Apparatus Mediated by Vesicles. 
    153   Cytoplasmic Ubiquitin Ligase Complex  A Ubiquitin Ligase Complex Found in the Cytoplasm. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5829   Cytosol  The Part of the Cytoplasm That Does Not Contain Organelles But Which Does Contain Other Particulate Matter Such As Protein Complexes. 
    5515   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). 
    19776   Atg8 Ligase Activity  Catalysis of the Covalent Attachment of the Ubiquitin Like Protein Atg8 to Substrate Molecules; Phosphatidylethanolamine Is a Known Substrate.
