UniProtKB - O92503 (VIE2_NPVBM)
Protein
E3 ubiquitin-protein ligase IE2
Gene
IE2
Organism
Bombyx mori nuclear polyhedrosis virus (BmNPV)
Status
Functioni
RING-finger E3 ubiquitin ligase that plays an important regulatory role during the initial stages of infection. Migrates to specific nuclear foci early in infection supposely to prepare the sites for viral replication by targeting and ubiquitinating host proteins.1 Publication
Catalytic activityi
- S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine + [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine. EC:2.3.2.27
