The mechanistic basis of cargo selection during Golgi maturation

Resident proteins of the Golgi recycle in vesicles and the protein GOLPH3 enables the COPI vesicle coat to accomplish this.

Pseudouridine RNA avoids immune detection through impaired endolysosomal processing and TLR engagement

Toll-like receptors (TLRs) 7 and 8 detect RNA degradation products to sense infection. However, modified nucleosides common in self-RNA—most notably pseudouridine—evade recognition. This study finds t...

Online Now: Structural basis for OAS2 regulation and its antiviral function Online now:

Structural basis for OAS2 regulation and its antiviral function

Merold and Bekere et al. reveal that OAS2 exists as a zinc-mediated dimer in an autoinhibited state, preventing autoreactivity to short RNAs. Dimer-to-monomer transition, dsRNA binding to a non-canonical interface, and targeting to the Golgi by myristoylation are necessary for OAS2 activation and restriction of viruses that form double membrane vesicles.
