    GO ID   Ontology GO Term Definition
    160   Phosphorelay Signal Transduction System  A Conserved Series of Molecular Signals Found in Prokaryotes and Eukaryotes; Involves Autophosphorylation of a Histidine Kinase and the Transfer of the Phosphate Group to an Aspartate That Then Acts As a Phospho Donor to Response Regulator Proteins. 
    6813   Potassium Ion Transport  The Directed Movement of Potassium Ions (k+) Into Out of or Within a Cell or Between Cells by Means of Some Agent Such As a Transporter or Pore. 
    71805   Potassium Ion Transmembrane Transport  A Process in Which a Potassium Ion Is Transported From One Side of a Membrane to the Other. 
    5887   Integral Component of Plasma Membrane  The Component of the Plasma Membrane Consisting of the Gene Products and Protein Complexes Having At Least Some Part of Their Peptide Sequence Embedded in the Hydrophobic Region of the Membrane. 
    8076   Voltage Gated Potassium Channel Complex  A Protein Complex That Forms a Transmembrane Channel Through Which Potassium Ions May Cross a Cell Membrane in Response to Changes in Membrane Potential. 
    16020   Membrane  A Lipid Bilayer Along with All the Proteins and Protein Complexes Embedded in It an Attached to It. 
    155   Phosphorelay Sensor Kinase Activity  Catalysis of the Phosphorylation of a Histidine Residue in Response to Detection of an Extracellular Signal Such As a Chemical Ligand or Change in Environment to Initiate a Change in Cell State or Activity. the Two Component Sensor Is a Histidine Kinase That Autophosphorylates a Histidine Residue in Its Active Site. the Phosphate Is Then Transferred to an Aspartate Residue in a Downstream Response Regulator to Trigger a Response. 
    5249   Voltage Gated Potassium Channel Activity  Enables the Transmembrane Transfer of a Potassium Ion by a Voltage Gated Channel. a Voltage Gated Channel Is a Channel Whose Open State Is Dependent On the Voltage Across the Membrane in Which It Is Embedded.
