    GO ID   Ontology GO Term Definition
    6826   Iron Ion Transport  The Directed Movement of Iron (fe) Ions Into Out of or Within a Cell or Between Cells by Means of Some Agent Such As a Transporter or Pore. 
    6879   Cellular Iron Ion Homeostasis  Any Process Involved in the Maintenance of an Internal Steady State of Iron Ions At the Level of a Cell. 
    6880   Intracellular Sequestering of Iron Ion  The Process of Binding or Confining Iron Ions in an Intracellular Area Such That They Are Separated From Other Components of a Biological System. 
    6892   Post Golgi Vesicle Mediated Transport  The Directed Movement of Substances From the Golgi to Other Parts of the Cell Including Organelles and the Plasma Membrane Mediated by Small Transport Vesicles. 
    6898   Receptor Mediated Endocytosis  An Endocytosis Process in Which Cell Surface Receptors Ensure Specificity of Transport. a Specific Receptor On the Cell Surface Binds Tightly to the Extracellular Macromolecule (the Ligand) That It Recognizes; the Plasma Membrane Region Containing the Receptor Ligand Complex Then Undergoes Endocytosis Forming a Transport Vesicle Containing the Receptor Ligand Complex and Excluding Most Other Plasma Membrane Proteins. Receptor Mediated Endocytosis Generally Occurs Via Clathrin Coated Pits and Vesicles. 
    6955   Immune Response  Any Immune System Process That Functions in the Calibrated Response of an Organism to a Potential Internal or Invasive Threat. 
    8285   Negative Regulation of Cell Proliferation  Any Process That Stops Prevents or Reduces the Rate or Extent of Cell Proliferation. 
    48147   Negative Regulation of Fibroblast Proliferation  Any Process That Stops Prevents or Reduces the Frequency Rate or Extent of Multiplication or Reproduction of Fibroblast Cells. 
    55085   Transmembrane Transport  The Process in Which a Solute Is Transported From One Side of a Membrane to the Other. 
    55114   Oxidation Reduction Process  A Metabolic Process That Results in the Removal or Addition of One or More Electrons to or From a Substance with or Without the Concomitant Removal or Addition of a Proton or Protons. 
    61024   Membrane Organization  A Process Which Results in the Assembly Arrangement of Constituent Parts or Disassembly of a Membrane. a Membrane Is a 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. 
    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. 
    5829   Cytosol  The Part of the Cytoplasm That Does Not Contain Organelles But Which Does Contain Other Particulate Matter Such As Protein Complexes. 
    8043   Intracellular Ferritin Complex  A Ferritin Complex Located in the Cell. Intracellular Ferritin Complexes Contain 24 Subunits in a Mixture of L (light) Chains and H (heavy) Chains. 
    70062   Extracellular 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. Extracellular Exosomes Also Simply Called Exosomes Have a Diameter of About 40 100 Nm. 
    4322   Ferroxidase Activity  Catalysis of the Reaction: 4 Fe2+ + 4 H+ + O2 = 4 Fe3+ + 2 H2o. 
    5506   Iron Ion Binding  Interacting Selectively and Non Covalently with Iron (fe) Ions. 
    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). 
    8199   Ferric Iron Binding  Interacting Selectively and Non Covalently with Ferric Iron Fe(iii). 
    16491   Oxidoreductase Activity  Catalysis of an Oxidation Reduction (redox) Reaction a Reversible Chemical Reaction in Which the Oxidation State of an Atom or Atoms Within a Molecule Is Altered. One Substrate Acts As a Hydrogen or Electron Donor and Becomes Oxidized While the Other Acts As Hydrogen or Electron Acceptor and Becomes Reduced. 
    46872   Metal Ion Binding  Interacting Selectively and Non Covalently with Any Metal Ion.
