Description
Product Characteristics:
Forms 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.
Subcellular location: Cell membrane
Synonyms: IK1, SK4, KCA4, hSK4, IKCA1, hKCa4, KCa3.1, hIKCa1, Intermediate conductance calcium-activated potassium channel protein 4, SKCa 4, SKCa4, Putative Gardos channel, KCNN4
Target Information: The protein encoded by this gene is part of a potentially heterotetrameric voltage-independent potassium channel that is activated by intracellular calcium. Activation is followed by membrane hyperpolarization, which promotes calcium influx. The encoded protein may be part of the predominant calcium-activated potassium channel in T-lymphocytes. This gene is similar to other KCNN family potassium channel genes, but it differs enough to possibly be considered as part of a new subfamily. [provided by RefSeq, Jul 2008]
