[5] The KCa3.1 protein is part of a potentially heterotetrameric voltage-independent potassium channel that is activated by intracellular calcium.

The encoded protein may be part of the predominant calcium-activated potassium channel in T-lymphocytes.

[5] The channel activity was first described in 1958 by György Gárdos in human erythrocytes.
