a, Immunoblot of lysates of control or STRN1/3/4 KO 293A cells transfected with mock vector or indicated plasmids. b, Quantification of the ratios of phospho- and total proteins in a. c, Quantification of YAP localization in control or STRN1/3/4 KO 293A cells transfected with mock vector or indicated plasmids. d, Relative expression of YAP target genes CTGF and CYR61 in control or STRN1/3/4 KO 293A cells transfected with mock vector or indicated plasmids. Data in b–d are plotted as mean ± SEM of three biologically independent experiments. Results were evaluated by Two-tailed unpaired t tests (*, P<0.05; **, P<0.01; ***, P<0.001; ****, P<0.0001; ns, non-significant). Source data for graphs are available online.
