Description
DB1-VM1S1: SARS-CoV-2 Spike S1 (Delta B.1.617.2) Protein (DB1-VM1S1)
The spike protein (S) of coronavirus (CoV) attaches the virus to its cellular receptor, angiotensin-converting enzyme 2 (ACE2). A defined receptor-binding domain (RBD) on S mediates this interaction.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
