UBE2N

Ubiquitin-conjugating E2 ligase that has a role in the ubiquitination cascade for protein degradation.

Usage and Biology

This part encodes for the UBE2N enzyme which is a member of the E2 ubiquitin-conjugating enzyme family, it acts as the second enzyme in the ubiquitination cascade to receive the thioesterified ubiquitin from the E1 active site. Finally, The E3 ubiquitin ligase then promotes the transfer of ubiquitin onto the substrate by binding to both the protein substrate and the E2-bound ubiquitin. It interacts with the UBE2V2 (E2 ligase) to catalyze the formation of polyubiquitin chains. This protein may also be involved in DNA post replication repair, according to studies that have been done on mice.
