SARS-CoV-2 ORF3a Induces Incomplete Autophagy via the Unfolded Protein Response [PDF]
In the past year and a half, SARS-CoV-2 has caused 240 million confirmed cases and 5 million deaths worldwide. Autophagy is a conserved process that either promotes or inhibits viral infections.

SARS-CoV-2 ORF3a sensitizes cells to ferroptosis via Keap1-NRF2 axis
Viral infection-induced cell death has long been considered as a double-edged sword in the inhibition or exacerbation of viral infections. Patients with severe Coronavirus Disease 2019 (COVID-19) are characterized by multiple organ dysfunction syndrome ...

SARS-CoV-2 ORF3a accessory protein is a water-permeable channel that induces lysosome swelling [PDF]
ORF3a, the most abundantly expressed accessory protein of SARS-CoV-2, plays an essential role in virus egress by inactivating lysosomes through their deacidification. However, the mechanism underlying this process remains unclear.

Non-Synonymous Mutation Analysis of SARS-CoV-2 ORF3a in Indonesia
Background: The report of mutation sites ORF3a SARS CoV-2 in Indonesia is still limited. Some research showed that mutations in ORF3a protein might alter SARS-CoV-2 pathogenesis.
