High-resolution images provide clarity into how viral proteins are separated by a protease, an important step during virus replication that is targeted by an approved COVID-19 drug. UNIVERSITY PARK, ...

Researchers identified how the poxvirus protein VITF-3 forms a molecular ring that clamps onto DNA with viral RNA polymerase, ...

In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma ...

The rate of HIV infection continues to climb globally. Around 40 million people live with HIV-1, the most common HIV strain. While symptoms can now be better managed with lifelong treatment, there is ...

A research team at the University of Würzburg has deciphered another aspect of poxviral gene activation. They have revealed a unique viral mechanism: A molecular ring anchors the viral copying machine ...

This story is part of a larger series on viroids and virusoids, small infectious RNAs. It is also the sixth installment in a series on hepatitis D virus, a virusoid-like pathogen that causes serious ...

Human norovirus, a positive-strand RNA virus that is the leading cause of viral gastroenteritis accounting for an estimated 685 million cases and approximately 212,000 deaths globally per year, has no ...

This story is part of our series on viroids and virusoids, small infectious RNAs. The story is also the second installment in a series on hepatitis D virus, a virusoid-like pathogen that causes ...

Zika virus hijacks a key protein implicated in brain development for its own replication. Researchers led by Associate Professor Priya Shah at the University of California, Davis (CA, USA), have ...
