Preprint: Characterization of the emerging B.1.621 variant of interest of SARS-CoV-2
In this study, we reported the emergence and spread of the novel B.1.621 lineage of SARS-CoV-2, a new VOI with the insertion 146N and several amino acid substitutions in the Spike protein (T95I,Y144T, Y145S, R346K, E484K, N501Y and P681H). More...

UK SAGE: Lab studies suggest that the N501Y spike protein mutation increases binding to rat and mouse ACE2 leading to viral replication
A report issued by the UK government’s Scientific Advisory Group for Emergencies (SAGE) found the likelihood that a variant of concern (VOC) that has arisen in humans could infect a rodent and then spread among the animals is high. More...
