Caspase recruitment domain-containing protein 11 (CARD11)

Involved in the costimulatory signal essential for T- cell receptor (TCR)-mediated T-cell activation. Its binding to DPP4 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner.

Activates NF-kappa-B through BCL10 and IKK. Stimulates the phosphorylation of BCL10.
