SARS-CoV-2 Papain-Like Protease: Structure, Function and Inhibition.

ABSTRACT: Emerging variants of SARS-CoV-2 and potential novel epidemic coronaviruses underline the importance of investigating various viral proteins as potential drug targets. The papain-like protease of coronaviruses has been less explored than other viral proteins; however, its substantive role in viral replication and impact on the host immune response make it a suitable target to study. This review article focuses on the structure and function of the papain-like protease (PL^pro ) of SARS-CoV-2, including variants of concern, and compares it to those of other coronaviruses, such as SARS-CoV-1 and MERS-CoV. The protease's recognition motif is mirrored in ubiquitin and ISG15, which are involved in the antiviral immune response. Inhibitors, including GRL0617 derivatives, and their prospe
