Abstract:

Bcl10 is a key signaling intermediate in the TCR-to-NF-B pathway in Tlymphocytes. It is currently believed that, once activated, Bcl10 functions within a multiprotein signaling complex that activates the IKK complex. Bcl10 is thought to regulate this signaling complex, but how it transmits its signal through the complex is unknown. A thorough knowledge of Bcl10 biology is critical to understanding how Bcl10 functions and how it regulates its binding partners. In this study, we used mutational analysis, molecular imaging, biochemistry, and computerbioinformatics modeling to elucidate a structure and function for Bcl10. From our data, we identified a novel binding site forMALT1 within the Bcl10 protein, hypothesized that this site is completely separate and distinct from the binding sites of other Bcl10 signaling partners, and proposed two regulatory functions for the Bcl10 C-terminus.
