In addition, interaction of DPP4 with caveolin-1 may form a complex consisting of DOO4, CARMA1, Bcl10, MALT1, and I[kappa]B kinase in the lipid rafts on T cell membrane, leading to the activation of NF-[kappa]B [30].

Recognition of the participation of the CARMA-Bcl10-Malt1 (CBM) signalosome in vital processes in cells continues to emerge, including distinct roles of CARMA1 in immune cells and CARMA3 in epithelial/endothelial cells.
The assembly of the lipid raft-associated CARMA-Bcl10-MALT1 (CBM) signalosome involves CARMA1 in the immune cells and CARMA3 in nonimmune cells [23, 48, 49].

TCR dependent activation of NF-[kappa]B is mediated by a scaffold protein CARMA1, which belongs to the family of membrane associated guanylate kinases (MAGUK) [38-40].
