PKCβ phosphorylates (either directly or indirectly) the NF-κB signaling complex protein CARMA1 (the complex itself comprising CARMA1, BCL10, and MALT1).

These result in recruitment and summoning of the IKK (IkB kinase), TAK1 by several ubiquitylation enzymes also associated with the CARMA1/BCL10/MALT1 complex.
