    GO ID   Ontology GO Term Definition
    6260   DNA Replication  The Cellular Metabolic Process in Which a Cell Duplicates One or More Molecules of Dna. DNA Replication Begins When Specific Sequences Known As Origins of Replication Are Recognized and Bound by Initiation Proteins and Ends When the Original DNA Molecule Has Been Completely Duplicated and the Copies Topologically Separated. the Unit of Replication Usually Corresponds to the Genome of the Cell an Organelle or a Virus. the Template For Replication Can Either Be an Existing DNA Molecule or Rna. 
    6457   Protein Folding  The Process of Assisting in the Covalent and Noncovalent Assembly of Single Chain Polypeptides or Multisubunit Complexes Into the Correct Tertiary Structure. 
    6461   Protein Complex Assembly  The Aggregation Arrangement and Bonding Together of a Set of Components to Form a Protein Complex. 
    9408   Response to Heat  Any Process That Results in a Change in State or Activity of a Cell or an Organism (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of a Heat Stimulus a Temperature Stimulus Above the Optimal Temperature For That Organism. 
    34620   Cellular Response to Unfolded Protein  Any Process That Results in a Change in State or Activity of a Cell (in Terms of Movement Secretion Enzyme Production Gene Expression Etc.) As a Result of an Unfolded Protein Stimulus. 
    43241   Protein Complex Disassembly  The Disaggregation of a Protein Complex Into Its Constituent Components. Protein Complexes May Have Other Associated Non Protein Prosthetic Groups Such As Nucleic Acids Metal Ions or Carbohydrate Groups. 
    43335   Protein Unfolding  The Process of Assisting in the Disassembly of Non Covalent Linkages in a Protein or Protein Aggregate Often Where the Proteins Are in a Non Functional or Denatured State. 
    51085   Chaperone Mediated Protein Folding Requiring Cofactor  The Process of Assisting in the Correct Posttranslational Noncovalent Assembly of Proteins Which Is Dependent On Additional Protein Cofactors. This Process Occurs Over One or Several Cycles of Nucleotide Hydrolysis Dependent Binding and Release. 
    70389   Chaperone Cofactor Dependent Protein Refolding  The Process of Assisting in the Restoration of the Biological Activity of an Unfolded or Misfolded Protein Which Is Dependent On Additional Protein Cofactors. This Process Occurs Over One or Several Cycles of Nucleotide Hydrolysis Dependent Binding and Release. 
    5737   Cytoplasm  All of the Contents of a Cell Excluding the Plasma Membrane and Nucleus But Including Other Subcellular Structures. 
    5886   Plasma Membrane  The Membrane Surrounding a Cell That Separates the Cell From Its External Environment. It Consists of a Phospholipid Bilayer and Associated Proteins. 
    16020   Membrane  Double Layer of Lipid Molecules That Encloses All Cells and in Eukaryotes Many Organelles; May Be a Single or Double Lipid Bilayer; Also Includes Associated Proteins. 
    166   Nucleotide Binding  Interacting Selectively and Non Covalently with a Nucleotide Any Compound Consisting of a Nucleoside That Is Esterified with (ortho)phosphate or an Oligophosphate At Any Hydroxyl Group On the Ribose or Deoxyribose. 
    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). 
    5524   ATP Binding  Interacting Selectively and Non Covalently with ATP Adenosine 5' Triphosphate a Universally Important Coenzyme and Enzyme Regulator. 
    8270   Zinc Ion Binding  Interacting Selectively and Non Covalently with Zinc (zn) Ions. 
    43531   Adp Binding  Interacting Selectively and Non Covalently with Adp Adenosine 5' Diphosphate. 
    44183   Protein Binding Involved in Protein Folding  Interacting Selectively and Non Covalently with Any Protein or Protein Complex (a Complex of Two or More Proteins That May Include Other Nonprotein Molecules) That Contributes to the Process of Protein Folding. 
    51082   Unfolded Protein Binding  Interacting Selectively and Non Covalently with an Unfolded Protein.
