Plpro/papain-like protease (His Tag) (recombinant sars-cov)

Protein Construction: A DNA sequence encoding the SARS-CoV (strain WH20) papain-like protease (PLpro) (AAX16193.1) (Glu1541-Tyr1859) was expressed with a polyhistidine tag at the C-terminus. Sequence: Glu1541-Tyr1859. Fusion tag: C-His Endotoxin: Please contact us for more information. Protein function: The coronaviral proteases, papain-like protease (PLpro) and 3C-like protease (3CLpro), are attractive antiviral drug targets because they are essential for coronaviral replication. PLpro has the additional function of stripping ubiquitin and ISG15 from host-cell proteins to aid coronaviruses in their evasion of the host innate immune responses. Targeting PLpro with antiviral drugs may have an advantage in not only inhibiting viral replication but also inhibiting the dysregulation of signaling cascades in infected cells that may lead to cell death in surrounding, uninfected cells. Protein function: [Isoform Replicase polyprotein 1ab]: Multifunctional protein involved in the transcription and replication of viral RNAs. Contains the proteinases responsible for the cleavages of the polyprotein. [The UniProt Consortium]
