A Method to Monitor Activity of SARS-CoV-2 Nsp3 from Cells

Methods Mol Biol. 2023:2591:269-282. doi: 10.1007/978-1-0716-2803-4_16.

Abstract

SARS-CoV-2 protease Nsp3 is a therapeutic target for developing anti-SARS-CoV-2 drugs. Nsp3 is a large multi-spanning membrane protein, and its characterization in vitro has been challenging. Here we describe an in vitro assay to characterize the biochemical activity of full-length Nsp3 isolated from cells. The assay can be used to evaluate Nsp3 inhibitors.
