SARS-CoV-2 nsp9 Antibody (HL1399) - Azide and BSA Free

SARS-CoV-2 Nonstructural Protein 9 (NSP9) is one of the sixteen nonstructural proteins of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causative agent of COVID-19 (1). SARS-CoV-2 NSP9 is 113 amino acids (aa) with a theoretical molecular weight of 12.4 kDa (1-3). The amino acid sequence alignment of SARS-CoV and SARS-CoV-2's NSP9 has 97.3% sequence identity and 99.1% sequence similarity (1). Structurally NSP9 has a N-terminal beta-barrel made of seven beta-strands and a C-terminal alpha-helix (3). In SARS-CoV, NSP9 is important for viral proliferation; it is unclear if NSP9 plays the same role in SARS-CoV-2 but given the high degree of sequence similarity it is quite likely (4). SARS-CoV-2 NSP9 also plays a role in formation of nuclear transport machinery and the extracellular matrix (2). Additionally, NSP9 binds mind bomb 1 (MIB1), an E3 ubiquitin ligase that regulates antiviral innate immune signaling (2).
