BIOLOG
ical Activity

Inhibitor of Bmi1/Ring1A, subunits of the polycomb repressive complex 1 (PRC1); inhibits self-ubiquitination (IC
50
= 3.9
μ
M) but does not increase cellular levels of either subunit. Prevents Bmi1/Ring1A-mediated ubiquitination and drug-induced degradation of topoisomerase 2
α
(Top2
α
). Also shown to inhibit the
in vitro
E3 ubiquitin ligase activity of RNF2 and a Bmi1/RNF2 complex, inhibiting H2A/H2AX ubiquitination. Blocks polycomb repressor complex (PRC) 1-mediated histone H2A ubiquitination
in vitro
and
in vivo
.
