Introduction | Human Ubquitin Conjµgating Enzyme 9 (Ubc9) is a member of the E2 family and is specific for the conjµgation of SUMO to a variety of target proteins. SUMO conjµgation to target proteins is mediated by a different, but analogous, pathway to ubiquitinylation. This E2 is unusual in that it interacts directly with protein substrates that are modified by sumolyation, and may play a role in substrate recognition. Ubc9 can mediate the conjµgation of SUMO-1 to a variety of proteins including RanGAP1, I?B?, and PML without the requirement of an E3 ligase. |
Synonyms | SUMO-conjµgating enzyme UBC9, EC 6.3.2.-, SUMO-protein ligase, Ubiquitin-conjµgating enzyme E2 I, Ubiquitin-protein ligase I, Ubiquitin carrier protein I, Ubiquitin carrier protein 9, p18, UBC9, C358B7.1. |
Source | Escherichia Coli. |
Physical Appearance | Sterile Filtered white lyophilized powder. |
Formulation | Lyophilized from a 0.2μm filtered concentrated (1mg/ml) solution in 1X PBS and 1mM DTT, pH 7.5. |
Solubility | It is recommended to reconstitute the lyophilized UBE2I in sterile water not less than 100 |
