SARS-CoV-2 (2019-nCoV) Spike S1 Protein (RBD = receptor binding domain): The SARS-CoV-2 genome encodes for a spike protein, an envelope protein, a Introduction membrane protein, and a nucleoprotein. The spike (S) glycoprotein of coronaviruses is essential for binding of the virus to the host cell at the beginning of the infection process. Of particular note is the amino acid sequence Arg-Gly-Asp (RGD) at position 403-405 of the spike protein. These 3 amino acids are conserved in all known SARS-Co-2 viruses, but not in other types of coronavirus.
Outside of SARS-CoV-2, the RGD sequence occurs particularly in proteins of the extracellular matrix (connective tissue), for example in fibronectin and vitronectin. This enables cells to bind to the RGD sequence with the help of certain cell surface receptors, the integrins. In addition to the SARS-CoV-2 viruses, well-known viruses such as HMPV, HCV or EBV also use the RGD to penetrate the cell.
The SARS-CoV-2 spike (S) glycoprotein is responsible for membrane fusion and is therefore required for cell fusion and virus entry. The spike protein is also a major immunogen and a possible target for inhibitors.
The SARS-CoV-2 spike (S) protein is a large type I transmembrane protein composed of two subunits, S1 and S2. The S1 subunit contains a receptor-binding domain (RBD) responsible for binding to the host cell receptor angiotensin-converting enzyme 2 (ACE2). The S2 subunit mediates fusion between the viral and host cell membranes. The S1 RBD protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.

SARS-CoV-2 (2019-nCoV) Spike S1 Protein can be used for the development of diagnostic kits. It is not for direct detection of SARS-Cov-2. The counterpart to SARS-CoV-2 is ACE2 (angiotensin converting enzyme-2), which has previously been described as a receptor for SARS-CoV.
