It's been reported that Coronavirus can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor.
The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2.
S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor.
S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.
特徴
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 26.6 kDa.
The protein migrates as 33-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

Source：SARS-CoV-2 S protein RBD (N501Y), His Tag (SPD-C52Hn) is expressed from human 293 cells (HEK293). It contains AA Arg 319 - Lys 537 (Accession # QHD43416.1 (N501Y)). The N501Y mutaion was identified in multiple SARS-CoV-2 Variants of Concerns (VOCs), i.e. the Alpha variant (Pango lineage: B.1.1.7; other names: 20I/501Y.V1 or VOC 202012/01), the Beta variant (Pango lineage: B.1.351; other names: 20H/501Y.V2), the Gamma variant (Pango lineage: P.1; other names: 20J/501Y.V3).
