Involvement of Dominant-negative Spliced Variants of the Intermediate Conductance Ca2+-activated K+ Channel, KCa3.1, in Immune Function of Lymphoid Cells

Abstract excerpt

The intermediate conductance Ca(2+)-activated K(+) channel (IK(Ca) channel) encoded by K(Ca)3.1 is responsible for the control of proliferation and differentiation in various types of cells. We identified novel spliced variants of K(Ca)3.1 (human (h) K(Ca)3.1b) from the human thymus, which were lacking the N-terminal domains of the original hK(Ca)3.1a as a result of alternative splicing events. hK(Ca)3.1b was...
