    Chain A
    GO ID   Ontology GO Term Definition
    2576   Platelet Degranulation  The Regulated Exocytosis of Secretory Granules Containing Preformed Mediators Such As Histamine and Serotonin by a Platelet. 
    6953   Acute Phase Response  An Acute Inflammatory Response That Involves Non Antibody Proteins Whose Concentrations in the Plasma Increase in Response to Infection or Injury of Homeothermic Animals. 
    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. 
    7599   Hemostasis  The Stopping of Bleeding (loss of Body Fluid) or the Arrest of the Circulation to an Organ or Part. 
    10466   Negative Regulation of Peptidase Activity  Any Process That Stops or Reduces the Rate of Peptidase Activity the Hydrolysis of Peptide Bonds Within Proteins. 
    10951   Negative Regulation of Endopeptidase Activity  Any Process That Decreases the Frequency Rate or Extent of Endopeptidase Activity the Endohydrolysis of Peptide Bonds Within Proteins. 
    30162   Regulation of Proteolysis  Any Process That Modulates the Frequency Rate or Extent of the Hydrolysis of a Peptide Bond or Bonds Within a Protein. 
    30168   Platelet Activation  A Series of Progressive Overlapping Events Triggered by Exposure of the Platelets to Subendothelial Tissue. These Events Include Shape Change Adhesiveness Aggregation and Release Reactions. When Carried Through to Completion These Events Lead to the Formation of a Stable Hemostatic Plug. 
    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. 
    5578   Proteinaceous Extracellular Matrix  A Layer Consisting Mainly of Proteins (especially Collagen) and Glycosaminoglycans (mostly As Proteoglycans) That Forms a Sheet Underlying or Overlying Cells Such As Endothelial and Epithelial Cells. the Proteins Are Secreted by Cells in the Vicinity. an Example of This Component Is Found in Mus Musculus. 
    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. 
    5783   Endoplasmic Reticulum  The Irregular Network of Unit Membranes Visible Only by Electron Microscopy That Occurs in the Cytoplasm of Many Eukaryotic Cells. the Membranes Form a Complex Meshwork of Tubular Channels Which Are Often Expanded Into Slitlike Cavities Called Cisternae. the Er Takes Two Forms Rough (or Granular) with Ribosomes Adhering to the Outer Surface and Smooth (with No Ribosomes Attached). 
    5794   Golgi Apparatus  A Compound Membranous Cytoplasmic Organelle of Eukaryotic Cells Consisting of Flattened Ribosome Free Vesicles Arranged in a More or Less Regular Stack. the Golgi Apparatus Differs From the Endoplasmic Reticulum in Often Having Slightly Thicker Membranes Appearing in Sections As a Characteristic Shallow Semicircle So That the Convex Side (cis or Entry Face) Abuts the Endoplasmic Reticulum Secretory Vesicles Emerging From the Concave Side (trans or Exit Face). in Vertebrate Cells There Is Usually One Such Organelle While in Invertebrates and Plants Where They Are Known Usually As Dictyosomes There May Be Several Scattered in the Cytoplasm. the Golgi Apparatus Processes Proteins Produced On the Ribosomes of the Rough Endoplasmic Reticulum; Such Processing Includes Modification of the Core Oligosaccharides of Glycoproteins and the Sorting and Packaging of Proteins For Transport to a Variety of Cellular Locations. Three Different Regions of the Golgi Are Now Recognized Both in Terms of Structure and Function: Cis in the Vicinity of the Cis Face Trans in the Vicinity of the Trans Face and Medial Lying Between the Cis and Trans Regions.

    4867   Serine Type Endopeptidase Inhibitor Activity  Stops Prevents or Reduces the Activity of Serine Type Endopeptidases Enzymes That Catalyze the Hydrolysis of Nonterminal Peptide Bonds in a Polypeptide Chain; a Serine Residue (and a Histidine Residue) Are At the Active Center of the Enzyme. 
    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). 
    30414   Peptidase Inhibitor Activity  Stops Prevents or Reduces the Activity of a Peptidase Any Enzyme That Catalyzes the Hydrolysis Peptide Bonds. 
    42802   Identical Protein Binding  Interacting Selectively and Non Covalently with an Identical Protein or Proteins. 
    Chain B
    GO ID   Ontology GO Term Definition
    6508   Proteolysis  The Hydrolysis of Proteins Into Smaller Polypeptides And/or Amino Acids by Cleavage of Their Peptide Bonds. 
    3824   Catalytic Activity  Catalysis of a Biochemical Reaction At Physiological Temperatures. in Biologically Catalyzed Reactions the Reactants Are Known As Substrates and the Catalysts Are Naturally Occurring Macromolecular Substances Known As Enzymes. Enzymes Possess Specific Binding Sites For Substrates and Are Usually Composed Wholly or Largely of Protein But RNA That Has Catalytic Activity (ribozyme) Is Often Also Regarded As Enzymatic. 
    4252   Serine Type Endopeptidase Activity  Catalysis of the Hydrolysis of Internal Alpha Peptide Bonds in a Polypeptide Chain by a Catalytic Mechanism That Involves a Catalytic Triad Consisting of a Serine Nucleophile That Is Activated by a Proton Relay Involving an Acidic Residue (e.g. Aspartate or Glutamate) and a Basic Residue (usually Histidine).
