This family contains a number of ubiquitin-like proteins: SUMO (smt3 homologue) (see Swiss:Q02724), Nedd8 (see Swiss:P29595), Elongin B (see Swiss:Q15370), Rub1 (see Swiss:Q9SHE7), and Parkin (see Swiss:O60260). A number of them are thought to carry a distinctive five-residue motif termed the proteasome-interacting motif (PIM), which may have a biologically significant role in protein delivery to proteasomes and recruitment of proteasomes to transcription sites [5].

The SAGA (Spt-Ada-Gcn5-acetyltransferase) complex performs multiple functions in transcription activation including deubiquitinating histone H2B, which is mediated by a subcomplex called the deubiquitinating module (DUBm). The yeast DUBm comprises a catalytic subunit, Ubp8, and three additional subunits, Sgf11, Sus1 and Sgf73, all of which are required for DUBm activity. A portion of the non-globular Sgf73 subunit lies between the Ubp8 catalytic domain and the zinc finger (ZnF)-UBP domain and has been proposed to contribute to deubiquitinating activity by maintaining the catalytic domain in an active conformation. Sgf73 contributes to maintaining both the organization and ubiquitin-binding conformation of Ubp8, thereby contributing to overall DUBm activity. This domain is a Sgf73 fragment in the DUB module. It is a zinc finger (ZnF) domain whose integrity is essential for the incorporation of this subunit into DUBm as well as for the catalytic activity of Ubp8, as either a short deletion or point mutations in Sgf73 zinc-coordinating residues disrupt the association of Sgf73 with the rest of the DUBm [1 -4].
