EOG88SK71 GO:0005249 24/134 voltage-gated potassium channel activity molecular_function "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." [GOC:mtg_transport, ISBN:0815340729] EOG88SK71 GO:0016021 22/134 integral component of membrane cellular_component "The component of a 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." [GOC:dos, GOC:go_curators] EOG88SK71 GO:0000155 20/134 phosphorelay sensor kinase activity molecular_function "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."

[GOC:jl] EOG88SK71 GO:0004871 1/134 signal transducer activity molecular_function "Conveys a signal across a cell to trigger a change in cell function or state. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response." [GOC:go_curators] EOG88SK71 GO:0006813 1/134 potassium ion transport biological_process "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." [GOC:ai] EOG88SK71 GO:0042391 1/134 regulation of membrane potential biological_process "Any process that modulates the establishment or extent of a membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane."
