Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 50 kDa (predicted molecular weight: 47 kDa).


  • FunctionForms a voltage-independent potassium channel that is activated by intracellular calcium. Activation is followed by membrane hyperpolarization which promotes calcium influx. Required for maximal calcium influx and proliferation during the reactivation of naive T cells. The channel is blocked by clotrimazole and charybdotoxin but is insensitive to apamin.
  • Tissue specificityWidely expressed in non-excitable tissues.
  • Sequence similaritiesBelongs to the potassium channel KCNN family. KCa3.1/KCNN4 subfamily.
  • Post-translational
    Phosphorylation at His-358 by NDKB activates the channel, and conversely it's dephosphorylation by PHPT1 inhibits the channel.
