Guanine nucleotide-binding protein subunit beta-2-like 1(GNB2L1) also known as receptor of activated protein kinase C 1 (RACK1) is reported to associate with the IKK complex in a TNF-triggered manner (Yao F et al. 2014). This interaction interfered with TRAF2-mediated recruitment and the subsequent phosphorylation of IKK triggered by TNF. By modulating the interaction between TRAF2 and the IKK complex, GNB2L1 (RACK1) regulated the level of NFkB activation in response to TNF (Yao F et al. 2014).
