Previous GeneCards Identifiers for UBE2N Gene
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. Studies in mouse suggest that this protein plays a role in DNA postreplication repair. [provided by RefSeq, Jul 2008]
GeneCards Summary for UBE2N Gene
UBE2N (Ubiquitin-Conjugating Enzyme E2N) is a Protein Coding gene. Among its related pathways are PI-3K cascade and Class I MHC mediated antigen processing and presentation. GO annotations related to this gene include ubiquitin-protein transferase activity and ubiquitin binding. An important paralog of this gene is UBE2T.
UniProtKB/Swiss-Prot for UBE2N Gene
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 (By similarity).
Theubiquitin (Ub)/Ub-like (Ubl) conjugating enzymesare a conserved family of ligases which mediate the conjugation of Ub and Ubl proteins to target substrates. There have been 35 E2 enzymes identified in the human genome to date.
