CARD10/BIMP1 (CARMA3) physically binds BCL10 via its CARD domain and forms a ternary complex with BCL10 and MALT1 (with BCL10 bridging the BIMP1/MALT1 interaction). This complex activates NF-κB through IκB kinases, and a dominant-negative BIMP1 mutant inhibits NF-κB activation by anti-CD3 ligation, phorbol ester, and PKC expression, placing CARD10 upstream of IKK in the PKC-to-NF-κB signaling axis. |

CARMA3 physically associates with IKKγ/NEMO in non-lymphoid cells. CARMA3 participates in a large inducible complex containing IKKγ/NEMO, BCL10, and IKKα/β kinases. Expression of the NEMO-binding region of CARMA3 acts as a dominant negative, suppressing BCL10-mediated NF-κB activation, establishing direct physical and functional linkage between CARMA3 and the IKK complex. |

CARMA3 is required for angiotensin II (Ang II) receptor (type 1 GPCR)-induced NF-κB activation in hepatocytes. CARMA3, BCL10, and MALT1 form the CBM complex downstream of Ang II receptor; blocking any component via dominant-negative mutants, RNAi, or gene targeting abolishes Ang II-dependent NF-κB activation. The pathway activates NF-κB through ubiquitination of IKKγ/NEMO. |

CARMA3 is required for GPCR-induced IKK activation and NF-κB signaling. CARMA3-deficient mice generated by gene targeting show abrogated GPCR-induced NF-κB activation; CARMA3 physically associates with NEMO/IKKγ and induces polyubiquitination of NEMO-associated protein(s), likely by linking NEMO to TRAF6. CARMA3 deficiency impairs IKK kinase activity despite normal IKKα/β phosphorylation. |

PKCα links LPA receptor (GPCR) to CARMA3 for NF-κB activation and uPA upregulation in ovarian cancer cells. LPA stimulation activates PKCα and induces Ras-PKCα interaction; dominant-negative PKCα, but not PKCθ or PKCζ DN mutants, blocks LPA-induced NF-κB activation. Dominant-negative CARMA3 or siRNA silencing of CARMA3/BCL10/MALT1 abolishes LPA-induced NF-κB activation and invasion. |

Thrombin acting on PAR-1 (a GPCR) on endothelial cells uses the CARMA3·BCL10·MALT1 signalosome to link PKC activation to IKK stimulation and NF-κB-dependent ICAM-1/VCAM-1 expression, driving monocyte adhesion to endothelium. Unlike the lymphocyte CARMA1 signalosome, the CARMA3 endothelial signalosome does not require PDK1 but instead depends on β-arrestin 2 for assembly. |

Mechanistically, CARMA3 activates NF-κB, which drives miR-182 transcription (confirmed by ChIP and luciferase reporter assay), and miR-182 then suppresses NME2, a metastasis suppressor, thereby increasing cancer stemness and metastasis. |

CARMA3 positively regulates MAVS-induced NF-κB activation during RNA virus infection. Conversely, CARMA3 sequesters MAVS from forming high-molecular-weight aggregates, suppressing TBK1/IRF3 activation. After NF-κB activation, CARMA3 is degraded in a proteasome-dependent manner, releasing MAVS to activate IRF3. CARMA3-deficient mice show reduced inflammation and stronger viral clearance. |

CARD10 is the first identified MALT1 substrate in non-hematopoietic cells. MALT1 cleaves CARD10 at R587, and this cleavage dampens CARD10's capacity to activate NF-κB. Preventing CARD10 cleavage increases basal IL-6 and extracellular matrix components in vitro and leads to increased tumor growth in a mouse xenograft model, indicating that MALT1-mediated CARD10 cleavage is a built-in negative regulatory mechanism. |

In CARMA3-deficient mice, Con A-induced liver injury is exacerbated, with more LSEC damage, mitochondrial damage, and coagulation. In vitro, CARMA3-deficient LSECs show increased mitochondrial damage and cell death upon Con A treatment, revealing a mitochondria-protective role of CARMA3 in LSECs distinct from its NF-κB scaffolding function. |

Sonic hedgehog (SHH) signaling promotes myocardial pyroptosis after I/R injury via PKCα-mediated CARD10-BCL10-MALT1 (CBM) complex formation. SHH activation increases PKCα levels; PKCα inhibition attenuates CBM complex formation. Disruption of the CBM complex prevents MALT1 from recruiting TRAF6, which is required to trigger caspase-11-dependent pyroptosis. |
