Oligomerized Bcl10 facilitates the association with MALT1 to form the CBM signalosome. MALT1 possesses one death domain (DD) and 2 immunoglobulin-like domains (Ig-like) in its N-terminal region and a caspase like domain (CLD) in its C-terminal region. The region between amino acids 107 and 119 of Bcl10 bind to the two Ig-like domains of MALT1. After binding to CARMA1 and Bcl10 complex, MALT1 also undergoes oligomerization. Only the oligomerized forms of Bcl10 and MALT1 are capable of activating IKK.
