In a paradigm of cellular differentiation, human myoblast fusion, we investigated how a Ca(2+) influx, indispensable for fusion, is triggered. We show how newly expressed Kir2.1 K(+) channels, via their hyperpolarizing effect on the membrane potential, generate a window Ca(2+) current (mediated by alpha 1H T-type Ca(2+) channels), which causes intracellular Ca(2+) to rise.
