A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

“Understanding SARS-CoV-2 Variants through Reverse Genetics”

Abstract:

SARS-CoV-2 continues to circulate with a set of actively evolving subvariants of the Omicron variant. Much attention is focused on mutations in the Spike protein and their immune evasive properties but changes in other structural and non-structural proteins contribute importantly to viral evolution and attenuation. We developed molecular technologies to rapidly and safely assess the functional impact of genome-wide mutations. These include virus-like particles (VLPs), replicons and full-length infectious clones. Here we discuss how signature mutations in Beta, Delta and Omicron variants affect viral fitness and nonstructural and structural protein functions.
