Study: Spike Protein NTD mutation G142D in SARS-CoV-2 Delta VOC lineages is associated with frequent back mutations, increased viral loads, and immune evasion. Image Credit: Corona Borealis Studio ...

Distinct mutations were identified in the NTD of the spike protein at the W152 position. At this position, tryptophan was identified to be substituted by Leucine (W152L) or arginine (w152R), and ...
