SARS-CoV-2s viral protein interactions with host cell structures and processes. (A) SARS-C0V-2 spike (S) protein interacts with host cell receptors ACE2 and TMPRSS2 for cellular entry. (B) Host cell membrane structure proteins interact with SARS-CoV-2 membrane (M) proteins for viral morphogenesis. (C) Host cell lipid processing channels such as ER, Golgi, and ERGIC interact with the SARS-CoV-2 Envelope (E) protein. (D) Host RNA processing components interact with SARS-CoV-2 N, E and Nsp (1,8,9,16), encoded by the SARS-CoV-2 genome. (E) Several structural and non-structural proteins in the SARS-Co-V-2 genome interact with components of the host innate immune system.
