LY2090314 also inhibited the growth of K562 STAG2 R614* mutant leukemia cells that we had previously characterized (Antony et al., 2020; Figure 4—figure supplement 2G) as well as the two additional MCF10A RAD21- and SMC3-deficient clones (Figure 3—figure supplement 3G). Here, STAG2 is linked to leukemia.
