Researchers investigate dynamics and modifications of COVID-19 virus spike protein

When the coronavirus that causes COVID-19 infects human cells, the cell’s protein-processing machinery modifies the spike protein, making it more flexible and mobile, potentially increasing its possibility to contaminate other cells and evade antibodies, according to new research from the University of Illinois Urbana-Champaign.
