Ubiquitin-conjugating enzyme E2 variant 2 is a protein that in humans is encoded by the UBE2V2 gene.[5][6] Ubiquitin-conjugating enzyme E2 variant proteins constitute a distinct subfamily within the E2 protein family.

Structure

UBE2V2 has sequence similarity to other ubiquitin-conjugating enzymes but lack the conserved cysteine residue that is critical for the catalytic activity of E2s. The protein encoded by this gene also shares homology with ubiquitin-conjugating enzyme E2 variant 1 and yeast MMS2 gene product.[7]

Function

UBE2V2 has also been implicated as an intracellular sensor of reactive electrophilic species, which are present in high levels during periods of pathogenic and/or environmental stress.[8] The C69 residue of UBE2V2 is capable of binding with various RES. It has been shown that binding of RES to UBE2V2 promotes UBE2V2-mediated activation of Ube2N, another E2 protein that complexes with UBE2V2. Activated Ube2N has been shown to play a major role in promoting DNA-damage responses. Thus, UBE2V2 may promote genome integrity by directly sensing RES and effecting DNA damage responses.[9] It may also be involved in the differentiation of monocytes and enterocytes.[7]

Interactions

UBE2V2 has been shown to interact with HLTF.[10] Although UBE2V2 itself lacks ubiquitin-conjugating activity, it can interact with different Ubiquitin-conjugating enzymes to facilitate their catalytic activities.[11] For instance, UBE2V2 can complex with UBE2N to form a heterodimer capable of synthesizing Lys-63 linked polyubiquitin chains.[12] UBE2V2 may facilitate UBE2N activity by coordinating UBE2N's positioning to promote ubiquitin chain formation specifically at Lys-63, as the ubiquitin molecule has multiple potential Lysine binding sites.[13] Similarly, it has been shown that UBE2V2 interact with the ubiquitin-conjugating enzyme, Ubc13, to induce Ubc13 to adopt an active conformation that can create Lys-63 polyubiquitin chains on various substrates.[14]

Addition of Lys-63 polyubiquitin chains to intracellular targets is distinct from the canonical Lys-48 polyubiquitin chains in that Lys-63 chains do not mediate proteasomal degradation of its substrate.[15] Although their function remains poorly characterized, Lys-63 chains have been shown to regulate signaling pathways by either activating or inhibiting its target protein function.[16] For example, TRIM5alpha restriction of retroviral reverse-transcription is dependent on UBE2V2/UBE2N-mediated poly-ubiquitination.[17] UBE2V2 has been shown to regulate TRIM21 antiviral activity in an analogous manner.[18]
