FIGURE 3:

Regulation of Orai1 assembly and selectivity by α-SNAP is independent of Stim1 levels. (A) Representative photobleaching steps obtained from Stim1-mEos–expressing, store- depleted Stim1−/− MEF cells. (B) Histogram showing number of Stim1-mEos photobleaching steps vs. normalized frequency from store-depleted Stim1−/− MEFs treated with SCR or α-SNAP siRNA (600–700 spots). (C, D) Box-and-whisker plots of constitutive calcium (C) and sodium influx (D) measured from SCR or α-SNAP siRNA–treated Orai1−/− MEF cells transfected with Orai1-SS (40–70 cells). Top and bottom box boundaries represent 25th and 75th percentile values, respectively, the median is represented by a horizontal line within the box, and whiskers denote extreme 25% quartile values of the data. Student’s t-test p < 0.0001 (C) and 0.0175 (D).
