Recent studies suggest that nuclear factor κB-inducing kinase (NIK) is suppressed through constitutive proteasome-mediated degradation regulated by TRAF2, TRAF3 and cIAP1 or cIAP2. Here, we demonstrated that the degradation of NIK occurred upon assembly of a regulatory complex through TRAF3 recruitment of NIK and TRAF2 recruitment of cIAP1 and cIAP2. In contrast to TRAF2 and TRAF3, cIAP1 and cIAP2 seem to play redundant roles in the degradation of NIK, as inhibition of both cIAPs was required for noncanonical NF-κB activation and increased survival and proliferation of primary B lymphocytes. Furthermore, the lethality of TRAF3-deficient mice could be rescued by a single NIK gene, highlighting the importance of tightly regulated NIK.
