- Fig. 2 The BRCT domain of tPARP1 interacts with the Pol III complex. a U2OS-PARP1 knockout cells were transfected with the myc-empty vector (EV), myc-POLR3A, myc-POLR3B, or myc-POLR3F together with HA-mtPARP1, followed by IP and western blotting with the indicated antibodies. b mtPARP1 or full-length mPARP1 was ectopically expressed in U2OS-PARP1 knockout cells. IP was performed with IgG as a negative control. c U2OS-PARP1 knockout cells were transfected with the myc-empty vector (EV), myc-POLR3A, myc-POLR3B, or myc-POLR3F together with HA-mTARG1, followed by IP and western blotting with the indicated antibodies. d U2OS-PARP1 knockout cells were transfected with the HA-tagged truncation mutants of mtPARP1 together with myc-POLR3A (upper panel), myc-POLR3B (middle panel), or myc-POLR3F (lower panel). e U2OS-PARP1 knockout cells were transfected with the indicated combinations of HA-tagged mtPARP1 or mtPARP1 F473A mutant together with myc-POLR3A (upper panel), myc-POLR3B (middle panel), or myc-POLR3F (lower panel).
