This is ubiquitin-binding zinc finger (UBZ) domain found in DNA polymerase eta (EC:2.7.7.7). It is important in the recruitment of the polymerase to the stalled replication machinery in translesion synthesis. The UBZ domain adopts a classical C2H2 zinc-finger structure characterized by a beta-beta-alpha fold [1].	Domain
