SARS-CoV-2 Spike protein (S) is present on the surface of infected cells (Buchrieser et al, 2021). During COPI (retrograde) transport from Golgi to the ERGIC, leakage of the S protein can occur from vesicles, due to inefficient binding of Spike to COPI. As a result, S appears to leak to the surface where it accumulates and can direct the formation of multinucleate syncytia. Additional results indicate that S is not efficiently endocytosed from the cell surface (Cattin-Ortolá et al, 2021).
