Discovery and mechanism of K63-linkage-directed deubiquitinase activity in USP53
25 Nov 2024
Abstract excerpt
Ubiquitin-specific proteases (USPs) represent the largest class of human deubiquitinases (DUBs) and comprise its phylogenetically most distant members USP53 and USP54, which are annotated as catalytically inactive pseudoenzymes. Conspicuously, mutations within the USP domain of USP53 cause progressive familial intrahepatic cholestasis. Here, we report the discovery that USP53 and USP54 are active DUBs with high...
