    GO ID   Ontology GO Term Definition
    737   DNA Catabolic Process Endonucleolytic  The Chemical Reactions and Pathways Resulting in the Breakdown of DNA Involving the Hydrolysis of Internal 3' 5' Phosphodiester Bonds in One or Two Strands of Deoxyribonucleotides. 
    6308   DNA Catabolic Process  The Cellular DNA Metabolic Process Resulting in the Breakdown of DNA Deoxyribonucleic Acid One of the Two Main Types of Nucleic Acid Consisting of a Long Unbranched Macromolecule Formed From One or Two Strands of Linked Deoxyribonucleotides the 3' Phosphate Group of Each Constituent Deoxyribonucleotide Being Joined in 3' 5' Phosphodiester Linkage to the 5' Hydroxyl Group of the Deoxyribose Moiety of the Next One. 
    6915   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. 
    5576   Extracellular Region  The Space External to the Outermost Structure of a Cell. For Cells Without External Protective or External Encapsulating Structures This Refers to Space Outside of the Plasma Membrane. This Term Covers the Host Cell Environment Outside an Intracellular Parasite. 
    5634   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. 
    5635   Nuclear Envelope  The Double Lipid Bilayer Enclosing the Nucleus and Separating Its Contents From the Rest of the Cytoplasm; Includes the Intermembrane Space a Gap of Width 20 40 Nm (also Called the Perinuclear Space). 
    70062   Extracellular Vesicular Exosome  A Membrane Bounded Vesicle That Is Released Into the Extracellular Region by Fusion of the Limiting Endosomal Membrane of a Multivesicular Body with the Plasma Membrane. 
    3779   Actin Binding  Interacting Selectively and Non Covalently with Monomeric or Multimeric Forms of Actin Including Actin Filaments. 
    4518   Nuclease Activity  Catalysis of the Hydrolysis of Ester Linkages Within Nucleic Acids. 
    4519   Endonuclease Activity  Catalysis of the Hydrolysis of Ester Linkages Within Nucleic Acids by Creating Internal Breaks. 
    4520   Endodeoxyribonuclease Activity  Catalysis of the Hydrolysis of Ester Linkages Within Deoxyribonucleic Acid by Creating Internal Breaks. 
    4530   Deoxyribonuclease I Activity  Catalysis of the Endonucleolytic Cleavage of DNA to 5' Phosphodinucleotide and 5' Phosphooligonucleotide End Products. 
    4536   Deoxyribonuclease Activity  Catalysis of the Hydrolysis of Ester Linkages Within Deoxyribonucleic Acid. 
    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). 
    16787   Hydrolase Activity  Catalysis of the Hydrolysis of Various Bonds E.g. C O C N C C Phosphoric Anhydride Bonds Etc. Hydrolase Is the Systematic Name For Any Enzyme of EC Class 3. 
    16888   Endodeoxyribonuclease Activity Producing 5' Phosphomonoesters  Catalysis of the Hydrolysis of Ester Linkages Within Deoxyribonucleic Acids by Creating Internal Breaks to Yield 5' Phosphomonoesters.
