Pseudohost

Infectious virus can interact with specific receptor, resulting virus entry into host cells. For example, SARS-CoV-2 consists of four structural proteins, including S (spike), E (envelope), M (membrane), and N (nucleocapsid) proteins. S, M and E proteins create the viral envelope together, and N protein holds the SARS-CoV-2 RNA genome. As a key component, spike (S) was identified as the protein responsible for virus entry into human cells. https://viroantibody.creative-biolabs.com/category-pseudohost-396.htm
