This domain is found in the human E3-independent E2 ubiquitin-conjugating enzyme UBE2O and related proteins. UBE2O is involved in the monoubiquitination of diverse targets to mediate important processes such as targeting proteins for quality control, regulation of nuclear trafficking of chromatin-associated proteins and clearing ribosomes during erythropoiesis [1,2]. UBE2O is a multidomain protein composed of several SH3-like domains, UBC domain and a CR3 helix. The domain represented by this entry folds into an open beta-barrel with a typical SH3-like topology. This domain contains a large unstructured insertion that is rich with glycine residues.	Domain

UBE2O is involved in the monoubiquitination of diverse targets to mediate important processes such as targeting proteins for quality control, regulation of nuclear trafficking of chromatin-associated proteins and clearing ribosomes during erythropoiesis [1,2]. UBE2O is a multidomain protein composed of several SH3-like domains, UBC domain and a CR3 helix. The domain represented by this entry folds into two tandem intertwined beta-barrels each of which with typical SH3 topology [3]. This tandem SH3-like domain is involved in binding to NAP1L1, one of the major regulators of the UBE2O target selection [3].	Domain

UBE2O is a multidomain protein composed of several SH3-like domains, UBC domain and a CR3 helix. The domain represented by this entry folds into an open beta-barrel with typical SH3 topology. It binds ubiquitin via unique distinct interface and plays a key role in the UBE2O target selection [3].	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].
