These proteases are important targets for development of antiviral drugs that would inhibit viral replication and reduce mortality associated with outbreaks of SARS-CoV. PLpro is a cysteine protease located within the non-structural protein 3 (NS3) section of the viral polypeptide. PLPro activity is required to process the viral polyprotein into functional, mature subunits; specifically, PLPro cleaves a site at the amino-terminus of the viral replicase region. In addition to its role in viral protein maturation, PLPro possesses a deubiquitinating and deISGylating activity. In vivo, this protease antagonizes innate immunity by inhibiting IRF3-induced production of type I interferons.\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: Papain-like Protease; PLpro; PL-PRO; pp1a; Replicase polyprotein 1a\u003c\/p\u003e\n\n\u003cp\u003eDescription: Recombinant 2019-nCoV Papain-like Protease is produced by our E.coli expression system and the target gene encoding Glu1564-Lys1878 is expressed.\u003c\/p\u003e\n\n\u003cp\u003eAccession: QHD43415.1\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: 35.8 KDa\u003c\/p\u003e\n\n\u003cp\u003eApparent Molecular Weight: 34 KDa, reducing conditions\u003c\/p\u003e\n\n\u003cp\u003eStorage Condition: Lyophilized protein should be stored at \u0026lt; -20°C, though stable at room temperature for 3 weeks.
