Term Name: large conductance calcium-activated potassium channel activity Search Ontology:
Synonyms:
  • BK calcium-activated potassium channel activity
  • BK channel activity
  • BK KCa channel activity
  • large conductance KCa channel activity
Definition: Enables the transmembrane transfer of potassium by a channel with a unit conductance of 100 to 220 picoSiemens that opens in response to stimulus by concerted actions of internal calcium ions and membrane potential. Large conductance calcium-activated potassium channels are less sensitive to calcium than are small or intermediate conductance calcium-activated potassium channels. Transport by a channel involves catalysis of facilitated diffusion of a solute (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel, without evidence for a carrier-mediated mechanism.
