In the original version of this manuscript, we inadvertently included the incorrect blot for HSP90, a control for equal protein loading, in supplemental Fig. S3. The HSP90 signal shown in supplemental Fig. S3 was taken from the blot shown in Fig. 3B. In both of these experiments, primary antibodies against caspase-8 and HSP90 were used concurrently, so signals for both caspase-8 and the loading control HSP90 are visible on each blot. Below is the corrected version of Fig. S3 with the correct location of the HSP90 loading control shown. These changes do not affect the interpretation or conclusions of this work.
