NR-55277?? Spike Glycoprotein Receptor Binding Domain (RBD) from SARS-Related Coronavirus 2, Alpha Variant with C-Terminal Histidine Tag, Recombinant from HEK293 Cells(Proteins)|SARS-Related Coronavirus 2|Spike Glycoprotein Receptor Binding Domain (RBD) from SARS-Related Coronavirus 2, Alpha Variant with C-Terminal Histidine Tag, Recombinant from HEK293 Cells| -60°C or colder |F Krammer, F AmanatAcknowledgment for publications should read “The following reagent was obtained through BEI Resources, NIAID, NIH: Spike Glycoprotein Receptor Binding Domain (RBD) from SARS Related Coronavirus 2, Alpha Variant with C-Terminal Histidine Tag, Recombinant from HEK293 Cells, NR-55277.”|Quantity limit per order for this item is 1. This item can be ordered twice a year. Orders over this limit will be sent to NIAID for approval before shipment.
A recombinant form of the spike (S) glycoprotein receptor binding domain (RBD) from severe acute respiratory syndrome related coronavirus 2 (SARS-CoV-2), Alpha variant [also referred to as United Kingdom (UK) variant; B.1.1.7 lineage] was produced in human embryonic kidney HEK293 cells and purified by affinity chromatography. NR-55277 lacks the signal sequence and contains 223 residues of the SARS-CoV-2 S glycoprotein RBD and features a C-terminal hexa-histidine tag. NR-55277 is an Alpha variant of SARS-CoV 2, which includes a N501Y mutation in the S glycoprotein RBD as compared to the SARS-CoV-2 reference sequence (GenPept: QHD43416). NR-55277 has a theoretical molecular weight of 25,970 daltons. The crystal structure for trimeric S glycoprotein from SARS-CoV-2, B.1.1.7 lineage has been solved at 3.22 ? resolution (PDB: 7LWS).

The S glycoprotein mediates viral binding to the host angiotensin converting enzyme 2 (ACE2). This protein forms a trimer, and when bound to a host receptor allows fusion of the viral and cellular membranes. The Alpha variant of SARS-CoV-2 includes multiple mutations that were first identified in the United Kingdom, and the most studied is N501Y. Structural modeling and mouse studies indicate N501Y increases S glycoprotein binding to ACE2, resulting in increased SARS-CoV-2 virulence.
