Ubiquitin in the immune system

Correction to: EMBO reports 15: 28–45 DOI: 10.1002/embr.201338025

In this article, published in the January 2014 issue of EMBO reports, there definition of IPS in the Glossary was incorrect. The corrected definition is “IFN-β promoter stimulator.” In the legend to Figure 2, lines 2 and 3 should read “ε-amino group” instead of “α-amino group.” We apologize for any inconvenience caused.
