Cryo-EM structures of autoinhibited and RNA-activated ZNFX1 helicase
ZNFX1 is an RNA helicase that plays a critical role in host defense against viral infections. Recent studies further revealed that ZNFX1 harbors an unexpected RNA-ubiquitinating E3 ligase activity, raising fundamental questions about how RNA-binding activates this multifunctional enzyme. Here, we combine cryo-electro...
