Figure 3. Hap1 cells reconstituted with different SPCA1 isoforms and point mutations.
CRISPR-generated WT and KO clones of SPCA1 were reconstituted with (A and C) SPCA1 isoforms 1A-F and (B and D) isoform 1D bearing Hailey-Hailey disease-derived point mutations (G309C and D742Y) important in Ca2+-ion binding. Hap1 cells, un-reconstituted and reconstituted clones were infected with (A and B) RSV at a MOI of 0.1 and (C and D) hPIV-3-GFP at a MOI of 0.01. Cells, harvested (A and B) at 72 hpi and (C and D) at 48 hpi, were analyzed by flow cytometry and plotted as a percentage of GFP positive cells. See also Figures S1 and S2.
