    GO ID   Ontology GO Term Definition
    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. 
    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. 
    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). 
    1948   Glycoprotein Binding  Interacting Selectively and Non Covalently with a Glycoprotein a Protein That Contains Covalently Bound Glycose (monosaccharide) Residues. These Also Include Proteoglycans. 
    2020   Protease Binding  Interacting Selectively and Non Covalently with Any Protease or Peptidase. 
    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.
