This family includes the eukaryotic tumour susceptibility gene 101 protein (TSG101). Altered transcripts of this gene have been detected in sporadic breast cancers and many other human malignancies. However, the involvement of this gene in neoplastic transformation and tumorigenesis is still elusive. TSG101 is required for normal cell function of embryonic and adult tissues but that this gene is not a tumour suppressor for sporadic forms of breast cancer [1]. This family is related to the ubiquitin conjugating enzymes.	Domain

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].
