ON THE COVER
ROP18 is a key virulence factor in Toxoplasma gondii. Yamamoto et al. show that ROP18 targets the endoplasmic reticulum–bound transcription factor ATF6β, resulting in its destabilization and degradation. The watercolor image is an abstraction of ROP18 expression (purple) in a T. gondii parasite. Artwork by Emilie Clark (emilie{at}emilieclark.com).
