Abstract: Berberine (BBR), a traditional Chinese medicine, has therapeutic effects on a variety of inflammation-related diseases, but its direct proteomic targets remain unknown. Using activity-based protein profiling, we first demonstrated that BBR directly targets the NEK7 protein via the hydrogen bond between the 2,3-methylenedioxy and 121-arginine (R121) residues. The fact that R121 is located precisely within the key domain involved in the NEK7-NLRP3 interaction allows BBR to specifically block the NEK7-NLRP3 interaction and successively inhibit IL-1β release, independent of the NF-κB and TLR4 signaling pathways. Moreover, BBR displays in vivo anti-inflammatory efficacy in a NEK7-dependent manner. Therefore, we consider NEK7 to be a key target of BBR in the treatment of NLRP3-related inflammatory diseases, and the development of novel NEK7-NLRP3 interaction inhibitors might be easily achieved using NEK7 as a target.
