Background: SARS-CoV-2 ORF3a
The SARS-CoV-2 ORF3a protein encodes for a Ca2+ ion channel that functions in NLRP3 (NOD-, LRR- and pyrin domain-containing protein 3) inflammasome activation (3, 4). The ORF3a ion channel also functions in viral particle release as well as apoptotic and necrotic cell death (5). SARS-CoV-2 ORF3a interacts with the inflammasome component TRAF3 (TNF Receptor Associated Factor 3) which activates ASC (apoptosis-associated speck-like protein contain CARD) ubiquitination and, in-turn, stimulates caspase-1 activation and IL-1beta (interleukin-1-beta) production and maturation (3, 4). IL-1beta activation results in cytokine production and the overproduction of cytokines referred to as a cytokine storm, a hallmark of COVID-19 (4). Additionally, high throughput screening experiments have revealed the SARS-CoV-2 ORF3a binds to the human heme oxygenase (HMOX1) protein (5). HMOX1 has a role in reducing inflammation and tissue damage, both features of SARS-CoV-2 infection (5). The ORF3a-HMOX1 interaction will be worth exploring for its role in innate immune response and as a potential therapeutic target for COVID-19 (5).
Alternative names for SARS-CoV-2 ORF3a includes 2019-nCoV ORF3a protein, COVID-19 ORF3a, Human coronavirus ORF3a protein, ORF3a protein, SARS-CoV-2 accessory protein 3a, SARS-CoV-2 protein 3a, SARS-CoV-2 protein U274, and SARS-CoV-2 protein X1.
