Target Details

Target: SARS-CoV-2 Spike S2

Abstract: SARS-CoV-2 Spike S2 Products

Synonyms: E2 Protein, Surface Glycoprotein Protein, S Protein

Target Type: Viral Protein

Background: It's been reported that SARS-CoV-2 can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor. The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
