Effect of small polyanions on retroviruses

A retrovirus is a virus that inserts a copy of its genome into the DNA of a host cell that it invades, thus changing that cell's genome. Once inside the host cell's cytoplasm, the virus uses its reverse transcriptase enzyme ...

S-acylation enhances COVID-19 infection

Like many viruses, SARS-CoV-2 relies on lipid modifications carried by host enzymes to organize their membrane structure and coordinate the function of virulence proteins. Scientists at EPFL have discovered the enzymes that ...

Joining proteins together with rigid links

Researchers at the Paul Scherrer Institute PSI are the first to have joined two proteins together by means of a free-standing, rigid link. The structural element holds the two protein molecules together at a defined distance ...

Watching SARS-CoV-2 spread in animal models in real time

A version of SARS-CoV-2, the virus that causes COVID-19 disease, has been successfully modified to glow brightly in cells and animal tissues, providing a real-time way to track the spread and intensity of viral infection ...

Ancient marsupial 'junk DNA' might be useful after all

Fossils of ancient viruses are preserved in the genomes of all animals, including humans, and have long been regarded as junk DNA. But are they truly junk, or do they actually serve a useful purpose?

New CRISPR-Cas system cuts virus RNA

Researchers from the group of Stan Brouns (Delft University of Technology) have discovered a new CRISPR-Cas system that cuts RNA. The study will be published on August 26 in Science and is expected to offer many opportunities ...

Researchers shed new light on the molecular detail of COVID-19

Researchers from Western Sydney University have joined the global race to better understand COVID-19, with new research proposing how a SARS-CoV-2 protein (Nsp9), vital in the virus' life cycle, is supporting the replicating ...
