Correction for “ Con fi nement of caspase - 12 proteolytic activity to autoprocessing

BIOCHEMISTRY Correction for “Confinement of caspase-12 proteolytic activity to autoprocessing,” by Sophie Roy, Jeffrey R. Sharom, Caroline Houde, Thomas P. Loisel, John P. Vaillancourt, Wei Shao, Maya Saleh, and Donald W. Nicholson, which appeared in issue 11, March 18, 2008, of Proc Natl Acad Sci USA (105:4133–4138; first published March 10, 2008; 10.1073/pnas.0706658105). The authors note that Fig. 6 appeared incorrectly. There was an error in the alignment of the molecular mass markers, and minor adjustments have been made to the assignment of caspase12 bands. The authors also note that the source of the anticaspase-12 antibody for Fig. 6 was Sigma (clone 14F7). This error does not affect the conclusions of the article. The corrected figure and its corresponding legend appear below.
