Confocal z-series of the immunostaining for IP3R shown in Fig. 3A. For each of the four conditions shown in Fig. 3A, the movies show the complete series of sections (at 200-nm intervals) across each cell. (SV1) WT cells without TG treatment. (SV2) WT cells after TG treatment. (SV3) S224F/G1891S cells without TG treatment. (SV4) S224F/G1891S cells after TG treatment.
