Data Sheet: 
UBE2I (Ubc9) is a member of the E2 family and is homologous to ubiquitin-conjugating enzymes, but is specific for the conjugation of SUMO to a variety of target proteins. This E2 is unusual in that it interacts directly with protein substrates that are modified by SUMOylation, and may play a role in substrate recognition. In some cases, Ubc9 can mediate the conjugation of SUMO1, SUMO2 and SUMO3 to a variety of proteins including RanGAP1, IkBa, and PML without the requirement of an E3 ligase, although for some substrates a SUMO E3 ligase is required.
