a CARD (caspase recruitment domain) protein that belongs to the membrane-associated guanylate kinase (MAGUK) family. MAGUK proteins function as molecular scaffolds for the assembly of multiprotein complexes at specialized regions of the plasma membrane. Contains an N-terminal CARD domain, a central coiled-coil domain, and a C-terminal region containing a PDZ, an SH3, and a GUK. Its CARD domain associates with the CARD domain of BCL10. BCL10 activates NF-kappaB through the IkappaB kinase complex in response to upstream stimuli. Apparently activates NF-kappaB and induce the phosphorylation of BCL10. Detected in adult peripheral blood leukocytes, thymus, spleen and liver. Also found in promyelocytic leukemia HL-60 cells, chronic myelogenous leukemia K562 cells, Burkitt's lymphoma Raji cells and colorectal adenocarcinoma SW480 cells. Note: This description may include information from UniProtKB.
