This SARS-CoV-2 event is manually inferred from the SARS-CoV-1 event of viroporin 3a (ORF3a) interaction with caveolin-1 (CAV1). This assumption is supported by in silico studies of complex formation between SARS-CoV-2 3a and CAV1 (Gupta S et al. 2022).

While located in the ERGIC or Golgi apparatus SARS-CoV-1 3a binds to the regulator and scaffolding protein CAV1 (Padhan K et al. 2007). Through its interaction with CAV1, SARS-CoV-1 3a (ORF3a) protein may regulate virus uptake, as well as the trafficking of structural proteins.
