UBE2B
| View/Edit Human | View/Edit Mouse |
Ubiquitin-conjugating enzyme E2 B is a protein that in humans is encoded by the UBE2B gene.[3][4]
The modification of proteins with ubiquitin is an important cellular mechanism for targeting abnormal or short-lived proteins for degradation. Ubiquitination involves at least three classes of enzymes: ubiquitin-activating enzymes, or E1s, ubiquitin-conjugating enzymes, or E2s, and ubiquitin-protein ligases, or E3s. This gene encodes a member of the E2 ubiquitin-conjugating enzyme family. This enzyme is required for post-replicative DNA damage repair. Its protein sequence is 100% identical to the mouse, rat, and rabbit homologs, which indicates that this enzyme is highly conserved in eukaryotic evolution.[4]
Interactions
UBE2B has been shown to interact with RAD18.[5][6]
