The WNK1-selective inhibitor WNK-IN-11, had only modest effects on the disassembly–reassembly process (it inhibits only one of the four WNK kinases) but caused a dramatic and rapid (within 1 h) spheroid to fibril transition of GFP-MxA condensates in three different cancer cell lines (Figure 6A,B, Figure 7D and Figure 9B). Here, MX1 is linked to cancer.
