Caspase activation and recruitment domain of CARD9-like proteins Caspase activation and recruitment domain (CARD) similar to that found in CARD9. CARD9 is a central regulator of innate immunity and is highly expressed in dendritic cells and macrophages. Together with BCL10 (B-cell lymphoma 10) and Malt1 (mucosa-associated lymphoid tissue-lymphoma-translocation gene 1), it forms the M-CBM signalosome (the CBM complex in myeloid immune cells), which mediates activation of NF-kB and MAPK by ITAM-coupled receptors expressed on immune cells. CARD9 associates with BCL10 via a CARD-CARD interaction. In general, CARDs are death domains (DDs) found associated with caspases. They are known to be important in the signaling pathways for apoptosis, inflammation, and host-defense mechanisms. DDs are protein-protein interaction domains found in a variety of domain architectures. Their common feature is that they form homodimers by self-association or heterodimers by associating with other members of the DD superfamily including PYRIN and DED (Death Effector Domain). They serve as adaptors in signaling pathways and can recruit other proteins into signaling complexes. |
