Calcium-dependent inactivation of light-sensitive channels in Drosophila photoreceptors.

The Journal of general physiology - 1 Mar 1994

Hardie R C, Minke B

Abstract excerpt

Whole-cell voltage clamp recordings were made from photoreceptors of dissociated Drosophila ommatidia under conditions when the light-sensitive channels activate spontaneously, generating a "rundown current" (RDC). The Ca2+ and voltage dependence of the RDC was investigated by applying voltage steps (+80 to -100 mV) at a variety of extracellular Ca2+ concentrations (0-10 mM). In Ca(2+)-free Ringer large currents...
