New tool predicts changes that may make COVID variants more infectious
The first key step in SARS-CoV-2 infection is when the virus’ spike protein binds to the ACE2 receptor on human cells. Researchers at Penn State have created a novel framework that can predict with reasonable accuracy the amino-acid changes in the virus’ spike protein that may improve its binding to human cells and confer increased infectivity to the virus.
