Figure 4. Current traces and IStat(E) of CsR- Y57K and CsR-Y57K-R83Q at different extracellular pH values.

Figure 4

(a) Photocurrents of CsR-Y57K are characterized by strong outward-directed photocurrents at high pHo (550 ± 25 nm). (b) IStat(E) of stationary photocurrents of CsR-Y57K (550 ± 25 nm, normalized to pH 7.5 and +75 mV, pH 10 [n = 6], pH 7.5 [n = 9], pH 5 [n = 4]). (c) Photocurrents of CsR-Y57K-R83Q exhibit the properties of both single mutations but without huge amplitudes at high electrochemical loads (550 ± 25 nm). (d) IStat(E) of stationary photocurrents of CsR-Y57K (550 ± 25 nm, normalized to pH 5 and 0 mV, pH 10 [n = 9)], pH 7.5 [n = 9], pH 5 [n = 9]). Data were measured in oocytes and represent the mean ± SE.
