S protein

The S protein helps the virus attach and enter human cells.

Coronaviruses are covered with several types of "S proteins" (or E2) forming a crown of protein spikes on the surface of the virus.

The N protein encapsulates the genomic RNA, and the S protein forms viral projections.

The S protein interacts with the porcine aminopeptidase N (pAPN), a cellular receptor, to aide in its entry.

The prototypical holin is the lambda phage S protein, which assists the lambda phage R protein (lysin).

Each clone containing an in-frame insertion should encode a truncated α s protein with GFP at the carboxy-terminus due to a stop codon in the Kan r .

Roadmap to developing a recombinant coronavirus S protein receptor-binding domain (RBD-S) vaccine sor severe acute respiratory syndrome (SARS).

Novel subunit vaccine constructs for an S protein SARS vaccine based on the receptor binding domain (RBD) are being developed by the New York Blood Center.

FCoV type II is a recombinant virus type I with spike genes (S protein) replacement from FCoV by the canine enteric coronavirus (CCOV) spikes.

The change in level of the EP 2 receptor expression in the uterus may contribute to the increase in G S protein content and cAMP concentration in mid-gestation and the decrease at term [ 26 27 ] .
