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 human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 51.1 kDa.
The protein migrates as 60-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
