Figure 4. Sus1 plays a conserved role in the SAGA DUB module and in the TREX-2 complex.

Figure 4

As in the DUB module (left), Sus1 also forms an alpha-helical clamp in the TREX-2 complex (right), which contains two copies of Sus1 and one copy of Cdc31 bound to the extended N-terminal helix of Sac3.
