UBE2V1 (Uev1A) forms a heterodimer with Ubc13 and directs it toward Lys63-linked polyubiquitination for NF-κB activation, while the paralog Mms2-Ubc13 is required for DNA damage repair but not NF-κB activation; the two Uevs differentially modulate the length of K63-linked polyubiquitin chains produced by Ubc13. |

The Ubc13-Uev1A E2 complex is required for TNF-induced TRAF2 K63-linked polyubiquitination and oligomerization, GCKR ubiquitination/activation, and downstream SAPK/JNK pathway activation; disruption of Ubc13 inhibits these events without affecting ASK1 activation. |

UEV1A presents Lys63 of acceptor ubiquitin to Ubc13 to direct K63-linked chain synthesis; UEV1A suppresses modification of the substrate TRAF6 itself while promoting free K63-linked ubiquitin chain synthesis, indicating a UEV1A-independent substrate modification step and UEV1A-dependent chain elongation step. |

Overexpression of UEV1A alone is sufficient to activate NF-κB and upregulate the anti-apoptotic protein Bcl-2, conferring cell survival under serum deprivation and protection against diverse apoptotic stimuli; these effects are reversed by RNAi knockdown of UEV1, identifying Uev1A as a regulatory component of the NF-κB pathway. |

The Uev1A-Ubc13 complex interacts with RHBDF2 and, upon TNFα stimulation, cooperates with the E3 CHIP to catalyze K63-linked ubiquitination of RHBDF2, enhancing TACE maturation and subsequent shedding of the TNFα receptor, thereby acting as a negative feedback regulator of NF-κB signaling. |
