Caspase Recruitment Domain Family, Member 9 (CARD9) Antibody – Rabbit Polyclonal

The protein encoded by this gene is a member of the CARD protein family, which is defined by the presence of a characteristic caspase-associated recruitment domain (CARD). CARD is a protein interaction domain known to participate in activation or suppression of CARD containing members of the caspase family, and thus plays an important regulatory role in cell apoptosis. This protein was identified by its selective association with the CARD domain of BCL10, a postive regulator of apoptosis and NF-kappaB activation, and is thought to function as a molecular scaffold for the assembly of a BCL10 signaling complex that activates NF-kappaB. Several alternatively spliced transcript variants have been observed, but their full-length nature is not clearly defined. [provided by RefSeq, Jul 2008]

CARD9: Activates NF-kappa-B via BCL10. Defects in CARD9 are the cause of familial candidiasis type 2 (CANDF2). Chronic mucocutaneous candidiasis is characterized by impaired clearance of fungal infections and results in colonization and infections of the mucosa or skin, predominantly with Candida albicans. CANDF2 is an autosomal recessive chronic mucocutaneous candidiasis. 3 isoforms of the human protein are produced by alternative splicing.
