Gene Ontology (GO)

  • GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
  • GO:0070288 A protein complex that binds iron and acts as a major iron storage system. There are three major subclasses of ferritins: the classical ferritins (Ftn), the heme-containing bacterioferritins (Bfr) and the DNA-binding proteins from starved cells (Dps). Ftn and Bfr are made of 24 subunits, whereas Dps are smaller with 12 subunits. Ftn is found in most kindoms, while Bfr and Dps are restricted to prokaryotes.
  • GO:0008199 Binding to a ferric iron ion, Fe(III).
  • GO:0004322 Catalysis of the reaction: 4 Fe2+ + 4 H+ + O2 = 4 Fe3+ + 2 H2O.
  • GO:0020037 Binding to a heme, a compound composed of iron complexed in a porphyrin (tetrapyrrole) ring.
  • GO:0005506 Binding to an iron (Fe) ion.
  • GO:0140315 Binding to an iron ion to prevent it from interacting with other partners or to inhibit its localization to the area of the cell or complex where it is active.
  • GO:0006879 A homeostatic process involved in the maintenance of a steady state level of iron ions within a cell.
  • GO:0006826 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.
