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].
