See “Methods” for descriptions of parameters measured. τ-n and W-n represent the corresponding time constants and relative weights, expressed as percentages, derived from exponential fittings of the 1
The midpoints of inactivation (V1/2) and slope factors (k) were obtained from a single or double Boltzmann fit. Values are means ± S.E.; n, number of experiments; -, not applicable. For comparison, th
Whole-cell patch-clamp recordings of membrane currents and Fura-2 measurements of free intracellular calcium concentration ([Ca2+]i) were used to study calcium influx through receptor-activated cation
