SARS-CoV-2 S1 Protein RBD (L452R Mutation). Cat# abx160087. Supplier: abbexa.

Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2/COVID-19) Spike S1 Protein Receptor-Binding Domain (RBD) is a recombinant protein expressed in Insect cells.

The SARS-CoV-2 Spike Protein (S protein) is a viral protein that allows the entry of SARS-CoV-2 into human cells. The protein forms trimers on the viral capsid and binds to human Angiotensin Converting Enzyme 2 (ACE2) located on the cell surface. The protein has a cleavage site between the S1 and S2 subunits that is targeted by the human enzyme Furin, and it may also cause the development of a syncytium (cell fusion). Antibodies to S protein can prevent viral entry as well as target the virus for further immune action.

The L452R mutation is present in the B.1.429/B.1.427 (CAL.20C/Epsilon) variants first identified in California, USA.
