background:
Has no ubiquitin ligase activity on its own. The UBE2V1-UBE2N heterodimer catalyzes the synthesis of non-canonical poly-ubiquitin chains that are linked through Lys-63. This type of poly-ubiquitination activates IKK and does not seem to involve protein degradation by the proteasome. Plays a role in the activation of NF-kappa-B mediated by IL1B, TNF, TRAF6 and TRAF2. 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.

Subunit:
Heterodimer with UBE2N. Interacts (UBE2V2-UBE2Nheterodimer) with the E3 ligase STUB1 (via the U-box domain); thecomplex has a specific 'Lys-63'-linked polyubiquitination activity.Interacts with TRAF6.
Subcellular Location:
Nucleus. Note=Excluded from the nucleolus.
Tissue Specificity:
Highly expressed in thyroid, pancreas, spinalcord, lymph node, trachea, adrenal gland, bone marrow and pancreas.Detected at low levels in heart, breast, placenta, brain, liver,kidney, stomach and lung.
Similarity:
Belongs to the ubiquitin-conjugating enzyme family.
