Mutational analyses of c-FLIPR, the only murine short FLIP isoform, reveal requirements for DISC recruitment.

Abstract excerpt

Cellular FLICE-inhibitory protein (c-FLIP) proteins are known as potent inhibitors of death receptor-mediated apoptosis by interfering with caspase-8 activation at the death-inducing signaling complex (DISC). Among the three human isoforms, c-FLIP(long), c-FLIP(short) and c-FLIP(R), the latter isoform is poorly characterized. We report here the characterization of murine c-FLIP(R) and show that it is the only...
