摘要：

The "funny" (pacemaker) current has unusual characteristics, including activation on hyperpolarization, permeability to K+ and Na+, modulation by internal cAMP, and a tiny, single-channel conductance. In cardiac cells and neurons, pacemaker channels control repetitive activity and excitability. The recent cloning of HCN subunits provides new insight into the molecular basis for the funny channel properties.
