Before print:

In the version of this article initially published online, errors appeared in Figs. 1 and 4. These errors have been corrected in the print, PDF, and HTML versions of this article. In Fig. 1, Edc1 was misspelled as Ecd1 in the figure and the legend; and in Fig. 4, the poly(A) tails were missing in both panels.

Original and Corrected.

The Fig. 1 legend originally read:

“Structures based on PDB 4XR7 for Pan2–Pan3, PDB 4B8C for Ccr4–Caf1–CNOT1, PDB 6AM0 for Ecd1–Dcp1–Dcp2–Edc3, PDB 4C8Q for Pat1–Lsm1–7, and PDB 2Y35 for Xrn1.”

Corrected Fig. 1 legend:

“Structures based on PDB 4XR7 for Pan2–Pan3, PDB 4B8C for Ccr4–Caf1–CNOT1, PDB 6AM0 for Edc1–Dcp1–Dcp2–Edc3, PDB 4C8Q for Pat1–Lsm1–7, and PDB 2Y35 for Xrn1.”
