SARS-CoV-2 N-terminal domain modulates S1/S2 cleavage and spike-mediated functions

In a recent study posted to the bioRxiv* preprint server, researchers explored the role of the N-terminal domain (NTD) of the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) spike (S) protein in SARS-CoV-2 fusion with the host membranes and coronavirus disease 2019 (COVID-19).
