Ube2N also known as Ubc13 is a ubiquitin-conjugating enzyme with a molecular mass of around 17 kDa. It plays an important role in the ubiquitination process by forming a complex with Uev1A which assists in catalyzing the attachment of ubiquitin to substrate proteins. Expression of Ube2N is found in various tissues particularly in those with high rates of protein modification and signal regulation. Mechanically Ube2N works by forming polyubiquitin chains linked through lysine 63 on ubiquitin molecules a step essential for signaling rather than protein degradation.
Biological function summary

Ube2N has a significant role in DNA repair and immune response. It teams up with other proteins as part of larger complexes like the E2/E3 ligase complexes facilitating non-degradative polyubiquitin chains that activate signaling pathways. These chains contribute to the repair of DNA double-strand breaks by involving in the activation of DNA repair proteins and maintaining genomic integrity. Furthermore Ube2N is pivotal in modulating the immune response by activating NF-kB a transcription factor important for immune and inflammatory responses.

Pathways

Ube2N's activities impact the important signaling pathways such as NF-kB and DNA damage response pathways. In the NF-kB pathway K63-linked polyubiquitination by Ube2N leads to the activation of IKK complex subsequently mobilizing NF-kB to the nucleus to initiate transcription of immune genes. In DNA damage response Ube2N interacts with proteins like Ubc13 and Rnf8 to enhance DNA repair processes. These interactions highlight Ube2N's connection within a network of proteins maintaining cell health.

Ube2N is linked to cancer progression and immune system dysfunctions. Abnormal activity or expression of Ube2N can lead to unchecked cellular proliferation seen in various types of cancer. Additionally Ube2N associates with immune disorders where deregulated NF-kB activity contributes to chronic inflammation and auto-immune conditions. Its interaction partners like Uev1A can also play a role in the dysregulated pathways contributing to these diseases.

General info

Function

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. 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. Together with RNF135 and UB2V1, catalyzes the viral RNA-dependent 'Lys-63'-linked polyubiquitination of RIGI to activate the downstream signaling pathway that leads to interferon beta production (PubMed : 28469175, PubMed : 31006531). UBE2V1-UBE2N together with TRAF3IP2 E3 ubiquitin ligase mediate 'Lys-63'-linked polyubiquitination of TRAF6, a component of IL17A-mediated signaling pathway.

Sequence similarities

Belongs to the ubiquitin-conjugating enzyme family.

Post-translational modifications

Conjugation to ISG15 impairs formation of the thioester bond with ubiquitin but not interaction with UBE2V2.
