FLICE is activated by association with the CD95 death-inducing signaling complex (DISC)

FLICE is activated by association with the CD95 death-inducing signaling complex (DISC).

Upon activation, the apoptosis-inducing cell membrane receptor CD95 (APO-1/Fas) recruits a set of intracellular signaling proteins (CAP1-4) into a death-inducing signaling complex (DISC). In the DISC, CAP1 and CAP2 represent FADD/MORT1. CAP4 was identified recently as an ICE-like protease, FLICE, with two death effector domains (DED). Here we show that FLICE binds to FADD through its N-terminal...

Caspase-2 is activated at the CD95 death-inducing signaling complex in the course of CD95-induced apoptosis.

Caspase-2 was reported to be involved in a number of apoptotic pathways triggered by various stimuli. However, the molecular mechanism of procaspase-2 activation in the course of apoptosis remains poorly defined. In this report, we demonstrate that procaspase-2 is recruited to the CD95 (Fas/APO-1) death-inducing signaling complex (DISC) in human T- and B-cell lines. We show that procaspase-2 is...

Dynamics within the CD95 death-inducing signaling complex decide life and death of cells

This study explores the dilemma in cellular signaling that triggering of CD95 (Fas/APO-1) in some situations results in cell death and in others leads to the activation of NF-kappaB. We established an integrated kinetic mathematical model for CD95-mediated apoptotic and NF-kappaB signaling. Systematic model reduction resulted in a surprisingly simple model well approximating experimentally obse...
