How a virus blocks a cellular emergency access lane to the nucleus, STAT!
Abstract
Early in viral infection, the STAT1 transcription factor is rapidly transported into the nucleus using a nonconventional import mechanism to establish an antiviral state. In this issue, Xu et al. (2014) show how the Ebola virus VP24 protein precisely blocks specialized STAT1 import while leaving other cellular import processes intact.

Ebola virus VP24 targets a unique NLS binding site on karyopherin alpha 5 to selectively compete with nuclear import of phosphorylated STAT1.Cell Host Microbe. 2014 Aug 13;16(2):187-200. doi: 10.1016/j.chom.2014.07.008. Cell Host Microbe. 2014. PMID: 25121748 Free PMC article.
