Isoform 2 (CARD14) Antibody – Chicken Polyclonal

The protein encoded by this gene belongs to the membrane-associated guanylate kinase (MAGUK) family, a class of proteins that functions as molecular scaffolds for the assembly of multiprotein complexes at specialized regions of the plasma membrane. This protein is also a member of the CARD protein family, which is defined by carrying a characteristic caspase-associated recruitment domain (CARD). This protein shares a similar domain structure with CARD11 protein. The CARD domains of both proteins have been shown to specifically interact with BCL10, a protein known to function as a positive regulator of cell apoptosis and NF-kappaB activation. When expressed in cells, this protein activated NF-kappaB and induced the phosphorylation of BCL10. Two alternatively spliced variants of this gene encoding distinct isoforms have been reported.

CARD14: a protein containing a caspase recruitment domain (CARD) that functions as an activator of BCL10 and NF-kappaB signaling. CARD is a protein module that consists of 6 or 7 antiparallel alpha helices. It participates in signaling through highly specific protein-protein homophilic interactions. CARD proteins function as scaffolds for the assembly of multiprotein complexes at specialized regions of the plasma membrane. The CARD domain of CARD14 associates specifically with the CARD domains of CARD10 and BCL10, a signaling protein that activates NF-kB through the IkappaB kinase complex in response to upstream stimuli. When expressed in cells, CARD14 activates NF-kappaB and induces the phosphorylation of BCL10. A subgroup of primary lymphomas of the central nervous system have higher levels of CARD14 expression.
