CARMA proteins belong to the membrane-associated guan-ylate kinase-like (MAGUK) family of proteins that can function as molecular scaffolds that assist assembly of signal transduction molecules. CARMA1, CARMA2, and CARMA3 share high degrees of sequence and functional homology, but their tissue-specific distribution suggests that they serve distinct biological functions in different cell types. As with CARMA1, the CARD domain of CARMA2 has been shown to specifically interact with BCL10, a protein known to function as a positive regulator of cell apoptosis and NF-kB activation. When expressed in cells, this protein activated NF-kB and induced the phosphorylation of BCL10 Alternative splicing of CARMA2 results in isoforms that possess differential effects on NF-kB activation and endoplasmic reticulum stress-induced cell death.Synonyms: CARD-containing MAGUK protein 2, Caspase recruitment domain-containing protein 14
