Protein

Ubiquitin-conjugating enzyme E2 N

Gene

UBE2N

Organism
Macaca fascicularis (Crab-eating macaque) (Cynomolgus monkey)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript leveli

Functioni

The UBE2V1-UBE2N and UBE2V2-UBE2N heterodimers catalyze the synthesis of non-canonical 'Lys-63'-linked polyubiquitin chains. This type of polyubiquitination does not lead to protein degradation by the proteasome. Mediates transcriptional activation of target genes. Plays a role in the control of progress through the cell cycle and differentiation. Plays a role in the error-free DNA repair pathway and contributes to the survival of cells after DNA damage. Acts together with the E3 ligases, HLTF and SHPRH, in the 'Lys-63'-linked poly-ubiquitination of PCNA upon genotoxic stress, which is required for DNA repair. Appears to act together with E3 ligase RNF5 in the 'Lys-63'-linked polyubiquitination of JKAMP thereby regulating JKAMP function by decreasing its association with components of the proteasome and ERAD (By similarity). Promotes TRIM5 capsid-specific restriction activity and the UBE2V1-UBE2N heterodimer acts in concert with TRIM5 to generate 'Lys-63'-linked polyubiquitin chains which activate the MAP3K7/TAK1 complex which in turn results in the induction and expression of NF-kappa-B and MAPK-responsive inflammatory genes (By similarity).By similarity

Catalytic activityi

ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine.PROSITE-ProRule annotation

Enzyme regulationi

Activity is inhibited by binding to OTUB1, which prevents 'Lys-63'-linked polyubiquitination.By similarity

Interactioni

Subunit structurei

Heterodimer with UBE2V2. Interacts (UBE2V2-UBE2N heterodimer) with the E3 ligase STUB1 (via the U-box domain); the complex has a specific 'Lys-63'-linked polyubiquitination activity. Interacts with RNF8 and RNF168. Interacts with RNF11. Interacts with the E3 ligases, HLTF and SHPRH; the interactions promote the 'Lys-63'-linked polyubiquitination of PCNA upon genotoxic stress and lead to DNA repair. Interacts with ARIH2 (via RING-type 2). Interacts with OTUB1; leading to inhibit E2-conjugating activity (By similarity).By similarity
