In the next to the last sentence the residue was incorrectly listed as K357; it should have been K372.
The following is the correct sentence:
"The amount of intracellular p53 was also reduced by the Set9 mutant and by Set9 siRNA, and analysis of 35S-labeled p53 at various times after exposure to radiolabeled methionine indicated that Set9 stabilized chromatin-bound p53, an effect that depended on K372 (as did Set9 stimulation of p21 transcription)."
The summary with the corrected sentence is available online (http://stke.sciencemag.org/cgi/content/abstract/sigtrans;2004/260/tw422) starting 27 February 2007.
The original, incorrect sentence was
"The amount of intracellular p53 was also reduced by the Set9 mutant and by Set9 siRNA, and analysis of 35S-labeled p53 at various times after exposure to radiolabeled methionine indicated that Set9 stabilized chromatin-bound p53, an effect that depended on K357 (as did Set9 stimulation of p21 transcription)."
