Caspase recruitment domain-containing protein 8 (CARD8)

Inhibits NF-kappa-B activation.

May participate in a regulatory mechanism which coordinates cellular responses controlled by NF-kappa-B transcription element.

Might be a component of the inflammasome, a protein complex which also includes PYCARD, NALP2 and CASP1 and whose function would be the activation of proinflammatory caspases. .
