Following the 2019 emergence of SARS-CoV-2 and the COVID-19 pandemic, SARS-CoV is now often referred to as SARS-CoV-1. SARS-CoV-1 is a member of the Coronaviridae family of viruses (2). The genome of SARS-CoV-1 is similar to other coronaviruses, and is comprised of four key structural proteins: spike (S), envelope (E), membrane (M), and nucleocapsid (N) (3). Coronavirus spike proteins are class I fusion proteins that harbor an ectodomain, a transmembrane domain, and an intracellular tail (4,5). The highly glycosylated ectodomain projects from the viral envelope surface and facilitates attachment and fusion with the host cell plasma membrane. The ectodomain can be further subdivided into host receptor-binding domain (RBD) (S1) and membrane-fusion (S2) subunits, which are produced upon proteolysis by host proteases at the S1\/S2 junction, with possible secondary cleavage occurring at a downstream site (S2\/S2') (6). S1 and S2 subunits remain associated after cleavage and assemble into crown-like homotrimers (3,5). As with SARS-CoV-2, the SARS-CoV-1 spike protein utilizes the angiotensin-converting enzyme 2 (ACE2) protein as a receptor for cellular entry (7-9). Spike protein subunits represent a key antigenic feature of coronavirus virions, and therefore represent an important target of vaccines, novel therapeutic antibodies, and small-molecule inhibitors (10,11).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nE2; E2 glycoprotein precursor; Peplomer protein; S glycoprotein; SARS-CoV spike protein; sars2; spike glycoprotein; SPIKE_CVHSA\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: Vir\nSENSITIVITY: Transfected Only\nMW (kDa): 200\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46800242540713,"sku":"26769T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-26769t","provider":"Iright","version":"1.0","type":"link"}
