SARS-CoV-2 ORF3a Antibody [CoraFluor™ 1]

Product Feature: CoraFluor Probes for TR-FRET

CoraFluor™ 1, amine reactive (Catalog:7920) and CoraFluor™ 2, amine reactive (Catalog # 7950) are terbium-based probes that have been developed for use as TR-FRET donors. They emit wavelengths compatible with commonly used fluorescent acceptor dyes such as BODIPY® (or BDY) and Janelia Fluor® dyes, FITC (Catalog # 5440), TMR and Cyanine 5 (Catalog # 5436). CoraFluor™ fluorescence is brighter and more stable in biological media than existing TR-FRET donors, leading to enhanced sensitivity and improved data generation. CoraFluor™ 1 exhibits excitation upon exposure to a 337 nm UV laser.

Background: SARS-CoV-2 ORF3a

SARS-CoV-2 Open Reading Frame 3a (ORF3a) is one of the nine downstream accessory protein open reading frames of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative agent of COVID-19 (1). SARS-CoV-2 ORF3a is 475 amino acids (aa) with a theoretical molecular weight of 31 kDa (1, 2). The amino acid sequence alignment of SARS-CoV and SARS-CoV-2's ORF3a has 72% sequence identity and 90% sequence similarity (3). Structurally, ORF3a is a homotetramer that is comprised of two non-covalently linked homodimers (2).

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.
