Co-localization of SVA 3D mutants with NLRP3 domains. PK-15 cells were transfected with EV together with Myc-NLRP3, Flag-3D together with myc-NLRP3, EV together with Myc-LRR, Flag-3D together with myc-LRR, EV together with Myc-NACHT, Flag-3D together with Myc-NACHT, EV together with Myc-PYD, Flag-3D together with Myc-PYD, EV together with Flag-3D-12, Flag-3D-12 together with Myc-NLRP3, EV together with Flag-3D-13, and Flag-3D-13 together with Myc-NLRP3. Subcellular localization was observed by confocal microscopy. The Pearson’s correlation coefficient was analyzed using the Image-J (Java 1.8.0_172) software. The scale bar was 10 μm.
