Ubiquitin-conjugating enzyme E2 E1 is a protein that in humans is encoded by the UBE2E1 gene.56

Function

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. Two alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.6

Interactions

UBE2E1 has been shown to interact with Ataxin 17 and NEDD4.89
