Immunogen
Protein S (PROS1) is glycoprotein and expressed in many cell types supporting its reported involvement in multiple biological
processes that include coagulation, apoptosis, cancer development and progression, and the innate immune response. Known
receptors bind S1 are ACE2, angiotensin-converting enzyme 2, DPP4, CEACAM etc.. The spike (S) glycoprotein of
coronaviruses is known to be essential in the binding of the virus to the host cell at the advent of the infection process. Most
notable is severe acute respiratory syndrome (SARS). The severe acute respiratory syndrome-coronavirus (SARS-CoV) spike
(S) glycoprotein alone can mediate the membrane fusion required for virus entry and cell fusion. It is also a major immunogen
and a target for entry inhibitors. It's been reported that 2019-nCoV 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 neutralizingantibody
and T-cell responses, as well as protective immunity.
