CARMA proteins are scaffold molecules that belong to the membrane-associated guanylate kinase-like (MAGUK) and the caspase-associated recruitment domain (CARD) protein families. They play critical role in antigen receptor signaling pathways. CARMA1, CARMA2, and CARMA3 share homologous sequence and function but are found in different tissues. CARMA1 is predominantly located in lymphoid tissue. CARMA1 protein associates with lipid rafts and interacts with Bcl10, that is required for activation of TCR induced NFkB signaling pathway. Specifically, CARMA1 N-terminal CARD domain binds to Bcl10 CARD motif. It is also essential for protein- induced IL-2 and INF-g production. CARMA genes deactivation studies in mice resulted in reduced immunoglobulin levels and absence of TCR-induced NFkB activation. This suggests that CARMA mutations may lead to adaptive and innate immunity malfunction.
