In the Ptpn11^D61G/+ row of Figure 1C on page 2306, the image taken at 60 s is incorrect; it is the same as the image taken at 120 s. The corrected Figure 1C is shown below.

In the Ptpn11^D61G/+ lanes of Figure 2D on page 2307, the incorrect western blots are shown in the LAT and PLCγ2 rows. The corrected Figure 2D is shown below; actin has been added as a new control loading.

In the Ptpn11^T468M/+ lanes of Figure 5E on page 2312, the incorrect western blots are shown in the Syk, pLAT Tyr 191, and LAT rows. The corrected Figure 5E is shown below; actin has been added as a new control loading.

In supplemental Figure 3B on page 8 of the supplemental Data, in the upper row of the images labeled “5 min,” the wild-type (WT) image was a duplicate of the Ptpn11^T468M/+ image.

The errors have been corrected in the online version of the article and the supplemental Data.
