Cul2/Rbx1 [untagged] is an insect cell-derived, functional human CUL2/RBX1 complex produced by coexpression in insect cells, validated indirectly through its ability to act as a substrate for neddylation in the presence of the NEDD8 E3 ligase His-DCNL2 and thioester-loaded His-UBE2M-NEDD8. Incubation of Cul2/Rbx1 and thioester loaded His-UBE2M- NEDD8 in the presence or absence of His-DCNL2 at 4°C was compared at two time points T0 and T2 minutes. Neddylation of the Cul2 subunit in the presence of His- DCNL2 was demonstrated.

Note

Cullin2 [Dac tagged]/Rbx1 was cleaved with TEV protease [6His tagged]. The Dac tag and TEV protease [6His-Tagged] were removed by capturing on amp sepharose and nickel resin respectively.
