    Chain A
    GO ID   Ontology GO Term Definition
    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. 
    6952   Defense Response  Reactions Triggered in Response to the Presence of a Foreign Body or the Occurrence of an Injury Which Result in Restriction of Damage to the Organism Attacked or Prevention/recovery From the Infection Caused by the Attack. 
    6954   Inflammatory Response  The Immediate Defensive Reaction (by Vertebrate Tissue) to Infection or Injury Caused by Chemical or Physical Agents. the Process Is Characterized by Local Vasodilation Extravasation of Plasma Into Intercellular Spaces and Accumulation of White Blood Cells and Macrophages. 
    7166   Cell Surface Receptor Signaling Pathway  A Series of Molecular Signals Initiated by Activation of a Receptor On the Surface of a Cell. the Pathway Begins with Binding of an Extracellular Ligand to a Cell Surface Receptor or For Receptors That Signal in the Absence of a Ligand by Ligand Withdrawal or the Activity of a Constitutively Active Receptor. the Pathway Ends with Regulation of a Downstream Cellular Process E.g. Transcription. 
    7267   Cell Cell Signaling  Any Process That Mediates the Transfer of Information From One Cell to Another. 
    7596   Blood Coagulation  The Sequential Process in Which the Multiple Coagulation Factors of the Blood Interact Ultimately Resulting in the Formation of an Insoluble Fibrin Clot; It May Be Divided Into Three Stages: Stage 1 the Formation of Intrinsic and Extrinsic Prothrombin Converting Principle; Stage 2 the Formation of Thrombin; Stage 3 the Formation of Stable Fibrin Polymers. 
    10629   Negative Regulation of Gene Expression  Any Process That Decreases the Frequency Rate or Extent of Gene Expression. Gene Expression Is the Process in Which a Gene's Coding Sequence Is Converted Into a Mature Gene Product or Products (proteins or Rna). This Includes the Production of an RNA Transcript As Well As Any Processing to Produce a Mature RNA Product or an MRNA (for Protein Coding Genes) and the Translation of That MRNA Into Protein. Some Protein Processing Events May Be Included When They Are Required to Form an Active Form of a Product From an Inactive Precursor Form. 
    19221   Cytokine Mediated Signaling Pathway  A Series of Molecular Signals Initiated by the Binding of a Cytokine to a Receptor On the Surface of a Cell and Ending with Regulation of a Downstream Cellular Process E.g. Transcription. 
    42517   Positive Regulation of Tyrosine Phosphorylation of Stat3 Protein  Any Process That Activates or Increases the Frequency Rate or Extent of the Introduction of a Phosphate Group to a Tyrosine Residue of a Stat3 Protein. 
    45087   Innate Immune Response  Innate Immune Responses Are Defense Responses Mediated by Germline Encoded Components That Directly Recognize Components of Potential Pathogens. 
    45581   Negative Regulation of T Cell Differentiation  Any Process That Stops Prevents or Reduces the Frequency Rate or Extent of T Cell Differentiation. 
    45892   Negative Regulation of Transcription DNA Templated  Any Process That Stops Prevents or Reduces the Frequency Rate or Extent of Cellular DNA Templated Transcription. 
    46597   Negative Regulation of Viral Entry Into Host Cell  Any Process That Stops Prevents or Reduces the Frequency Rate or Extent of the Entry of Viral Entry Into a Host Cell. 
    51607   Defense Response to Virus  Reactions Triggered in Response to the Presence of a Virus That Act to Protect the Cell or Organism. 
    60337   Type I Interferon Signaling Pathway  A Series of Molecular Signals Initiated by the Binding of a Type I Interferon to a Receptor On the Surface of a Cell and Ending with Regulation of a Downstream Cellular Process E.g. Transcription. Type I Interferons Include the Interferon Alpha Beta Delta Episilon Zeta Kappa Tau and Omega Gene Families. 
    60338   Regulation of Type I Interferon Mediated Signaling Pathway  Any Process That Modulates the Rate Frequency or Extent of a Type I Interferon Mediated Signaling Pathway. a Type I Interferon Mediated Signaling Pathway Is the Series of Molecular Events Generated As a Consequence of a Type I Interferon Binding to a Cell Surface Receptor. 
    2000552   Negative Regulation of T Helper 2 Cell Cytokine Production  Any Process That Stops Prevents or Reduces the Frequency Rate or Extent of T Helper 2 Cell Cytokine Production. 
    2000663   Negative Regulation of Interleukin 5 Secretion  Any Process That Stops Prevents or Reduces the Frequency Rate or Extent of Interleukin 5 Secretion. 
    2000666   Negative Regulation of Interleukin 13 Secretion  Any Process That Stops Prevents or Reduces the Frequency Rate or Extent of Interleukin 13 Secretion. 
    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. 
    5615   Extracellular Space  That Part of a Multicellular Organism Outside the Cells Proper Usually Taken to Be Outside the Plasma Membranes and Occupied by Fluid. 
    5125   Cytokine Activity  Functions to Control the Survival Growth Differentiation and Effector Function of Tissues and Cells. 
    5126   Cytokine Receptor Binding  Interacting Selectively and Non Covalently with a Cytokine Receptor. 
    5132   Type I Interferon Receptor Binding  Interacting Selectively and Non Covalently with an Interferon Type I Receptor a Heterodimeric Complex Composed of an Alpha Subunit (ifnar1) and a Beta Subunit (ifnar2). 
    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).
