Background

Target Background	SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2) also known as 2019-nCoV (2019 Novel Coronavirus) is a virus that causes illnesses ranging from the common cold to severe diseases. SARS-CoV-2 Spike Protein is composed of S1 domain and S2 domain. The spike protein mutation del 69-70 and N439K may help the virus escape the host's immune response.
Synonyms	SARS-CoV-2 S1 protein, del 69-70, N439K; 2019-nCoV S1 protein, del 69-70, N439K
