In the original version of this article, an author's name was misspelled. The correct spelling is Marvin J. Fritzler.

Additionally, in the first sentence of the Results section the word “some” is now added when describing SGs. In the same sentence, during the production process the term “Ras-GSP” was mistakenly inserted for “Ras-GAP.” The corrected sentence appears below.

Previous studies have shown that the composition of SGs varies with the stimulus used to elicit their assembly; e.g., heat shock–induced SGs contain HSP27, whereas arsenite-induced SGs do not (Kedersha et al., 1999), and some SGs containing G3BP (Ras-GAP SH3 domain–binding protein) have been described as lacking TIA-1 (Tourriere et al., 2003).
