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-κB activation. When expressed in cells, this protein activated NF-kappaB and induced the phosphorylation of BCL10.
The CARD14 gene was recently identified as the first gene directly linked to the most common form of Psoriasis. It has been suggested that a mutation in the gene plus an environmental trigger were enough to elicit plaque psoriasis.
