Figure 5From: Hyaluronan- and RNA-binding deubiquitinating enzymes of USP17 family members associated with cell viabilityDeubiquitinating enzyme assays for novel USP17 subfamily members. In vitro deubiquitinating enzyme activity for USP17K, USP17L, USP17M, and USP17N. Immunoblotting analysis was performed with anti-β-gal antiserum. Coexpressed plasmids were pGEX-2TK (lane 1), pGEX-2TK-USP17K (lane 2), pGEX-2TK-USP17K (C89S) (lane 3), pGEX-2TK-USP17L (lane 4), pGEX-2TK-USP17L (C89S) (lane 5), pGEX-2TK-USP17M (lane 6), pGEX-2TK-USP17M (C89S) (lane 7), pGEX-2TK-USP17N (lane 8), and pGEX-2TK-USP17N (C89S) (lane 9). All of normal USP17 subfamily members cleaved the linkage between ubiquitin and β-galactosidase.Back to article page
