Review[Anchoring proteins and cardiac sudden death: how and why?].
Mutations in proteins responsible for ion transport in cardiac tissue can induce a destabilization of electrical function and provoke cardiac sudden death. Identification of a genetic anomaly in a French family that developed the syndrome of cardiac sudden death has revealed a crucial new element in normal cardiac electrical function : Ion channels need to be anchored to specific domains at the plasma membrane by an anchoring protein called ankyrin-B.
