During viral replication, SARS-CoV-2 enters host cells through binding with ...

2) ...receptors on the cell surface. Once inside the cell, the virus releases its genetic material, which is in the form of RNA. The viral RNA then hijacks the host cell's machinery to replicate itself.
Within the Golgi apparatus, the viral RNA is translated into viral proteins..

3) ... by the host cell's ribosomes. These viral proteins undergo post-translational modifications and are processed within the Golgi apparatus. The Golgi apparatus also plays a role in assembling new viral particles.
After replication and assembly, the newly formed SARS-CoV-2 ..

A brief reminder
โ–ถ๏ธ The ERGIC (ER-Golgi intermediate compartment) is located at the interface between the endoplasmic reticulum (ER) and Golgi apparatus. It acts as a sorting station between these two organelles.

In this study,
Virion-transporting vesicles and pits at the plasma membrane were found to be coated with proteins. biorxiv.org/content/10.110โ€ฆ

7) Immunofluorescence and electron microscopy showed the coat protein was coatomer complex I (COPI).
The results identify COPI as critical for facilitating transport of virions from the ERGIC, revealing a novel role for COPI in the SARS-CoV-2 life cycle.
