PRT4165 is a Bmi1/Ring1A inhibitor with an IC50 of 3.9 ?M in the cell-free assay and also inhibits PRC1-mediated H2A ubiquitylation in vivo and in vitro.

PRT4165 is a potent inhibitor of PRC1-mediated H2A ubiquitylation in vivo and in vitro. It inhibits the accumulation of all detectable ubiquitin at sites of DNA double-strand breaks (DSBs), the retention of several DNA damage response proteins in foci that form around DSBs, and the repair of the DSBs. PRT4165 inhibits both RNF2 and RING 1A, which are partially redundant paralogues that together account for the E3 ubiquitin ligase activity found in PRC1 complexes, but not RNF8 nor RNF168. U2OS cells treated with increasing concentrations of PRT4165 show increasing numbers of cells in G2/M[2].

Cell lines: HeLa cells

Concentrations: 50 μM

Incubation Time: 5 h

Method: HeLa cells are transfected with Bmi1-FLAG, Ring1A and HA-ubiquitin. Twenty-four hours post transfection the cells are treated with either solvent (0.5% DMSO, 0.5% PEG400) or 50 μM PRT4165 for 5 hours. Bmi1-FLAG is immunoprecipitated from cell lysates, and conjugated ubiquitin is detected by Western-blot with anti-HA antibody.
