| + | CARD8 plays crucial roles in regulating apoptotic and inflammatory signaling pathways through the association of its caspase-recruitment domain (CARD) with those of procaspase-9 and procaspase-1. The CARD8 CARD has also been predicted to form an intramolecular complex with its FIIND domain. Here, the first crystal structure of the CARD8 CARD is reported; it adopts a six-helix bundle fold with a unique conformation of the alpha6 helix that is described here for the first time. The surface of the CARD8 CARD displays a prominent acidic patch at its alpha2, alpha3 and alpha5 helices that may interact with the procaspase-9 CARD, whereas an adjacent charged surface at its alpha3 and alpha4 helices may associate with the CARD8 FIIND domain without interfering with the CARD-CARD interaction. This suggests that the function of CARD8 may be regulated by both intramolecular and intermolecular interactions involving electrostatic attractions. | ||
