potassium calcium-activated channel subfamily N member 4
Alias
DHS2 | IK1 | IKCA1 | KCA4 | KCa3.1 | SK4 | hIKCa1 | hKCa4 | hSK4
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].
