SARS-CoV-2 NSP3 Protein (sf9, His)

SARS-CoV-2 NSP3 (NSP3) is one of non-structure protein that binds to viral RNA, nucleocapsid protein, as well as other viral proteins, and contributes in polyprotein processing. NSP3 has also an important role in innate immune response antagonism and is responsible for release of NSP1, NSP2, and NSP3 from the N-terminal region of pp1a and pp1ab. SARS-CoV-2 NSP3 Protein (sf9, His) is the recombinant Virus-derived SARS-CoV-2 NSP3 protein, expressed by Sf9 insect cells , with N-His labeled tag. The total length of SARS-CoV-2 NSP3 Protein (sf9, His) is 175 a.a., with molecular weight of ~19.87 kDa.

SARS-CoV-2 NSP3 (NSP3) is one of non-structure protein that binds to viral RNA, nucleocapsid protein, as well as other viral proteins, and contributes in polyprotein processing. NSP3 has also an important role in innate immune response antagonism and is responsible for release of NSP1, NSP2, and NSP3 from the N-terminal region of pp1a and pp1ab. NSP3 plays an important role in stimulating the translation of viral mRNAs which are capped but not polyadenylated, instead terminating in a conserved sequence 'GACC' at the 3' that is recognized by NSP3, which competes with host PABPC1 for EIF4G1 binding. The interaction between NSP3 and host EIF4G1 stabilizes the EIF4E-EIF4G1 interaction, thereby facilitating the initiation of capped mRNA translation^[1][2].
