Structural similarities between caspase 8 and FLIP. For details, refer to the text.

FIG. 2
Model for c-FLIP-mediated inhibition of procaspase 8 processing at the DISC. (A) The CD95 DISC. For details, refer to the text. (B to D) Depending on the ratio of procaspase 8 and c-FLIP proteins at the DISC (A, grey box), different products are released from the DISC upon receptor triggering. (B) Small amounts of c-FLIP proteins allow processing of procaspase 8, leading to the formation of the active caspase 8 heterotetramer composed of the p18 and p10 subunits. (C) In the presence of large amounts of c-FLIPL procaspase 8 is recruited into the DISC, and cleavage is blocked after generation of the p43 cleavage products of both caspase 8 and c-FLIPL. (D) In the presence of large amounts of c-FLIPS procaspase 8 is recruited into the DISC but remains unprocessed. In each case, modulation of caspase 8 cleavage renders cells resistant to CD95-mediated cell death.
