To investigate the effect of the killswitch on oncogenic NUP98::KDM5A condensates, we introduced doxycycline-inducible GFP-nb–KS and GFP-nb–KSF-to-A constructs in a stable AML cell line in which NUP98::KDM5A is tagged with an N-terminal GFP tag (Fig. 4f). This evidence concerns the gene NUP98 and acute myeloid leukemia.
