RNA’s mysterious folding process — ScienceDaily

A new Northwestern University-led study is unfolding the mystery of how RNA molecules fold themselves to fit inside cells and perform specific functions. The findings could potentially break down a barrier to understanding and developing treatments for RNA-related diseases, including spinal muscular atrophy and perhaps even the novel coronavirus. “RNA folding is a dynamic process […]
DeepMind solves 50-year-old challenge in predicting protein folding

Image credit: Science Photo Library/Getty Images This week, the artificial intelligence (AI) program, AlphaFold, developed by Google’s DeepMind, has solved a decades-old problem in biology: determining a protein’s 3D structure based only on its amino acid sequence. The results were announced at the 14th Community Wide Experiment on the Critical Assessment of Techniques for Protein […]
Folding of SARS-CoV2 genome reveals drug targets — and preparation for ‘SARS-CoV3’ — ScienceDaily

For the first time, an international research alliance has observed the RNA folding structures of the SARS-CoV2 genome with which the virus controls the infection process. Since these structures are very similar among various beta corona viruses, the scientists not only laid the foundation for the targeted development of novel drugs for treating COVID-19, but […]
Folding of SARS-CoV2 genome reveals drug targets — and preparation for ‘SARS-CoV3’

The genetic code of the SARS-CoV2 virus is exactly 29,902 characters long, strung through a long RNA molecule. It contains the information for the production of 27 proteins. This is not much compared to the possible 40,000 kinds of protein that a human cell can produce. Viruses, however, use the metabolic processes of their host […]
Folding proteins feel the heat, and cold

An illustration shows the dynamics of protein folding in a solution as previously understood and as revealed by new models developed at Rice University, Tulane University and the Johns Hopkins University School of Medicine.

RNA folding may help explain how the coronavirus became so hard to stop after it spilled over from wildlife to humans — ScienceDaily

We know that the coronavirus behind the COVID-19 crisis lived harmlessly in bats and other wildlife before it jumped the species barrier and spilled over to humans. Now, researchers at Duke University have identified a number of “silent” mutations in the roughly 30,000 letters of the virus’s genetic code that helped it thrive once it […]
