Active Recombinant Human USP20, GST-tagged

• Cat.No.: USP20-162H
• Product Overview: Recombinant human USP20 (amino acid residues 1-913), fused with N-terminal GST, was expressed in Insect sf21.

Specification

• Description: There are two main classes of DUB, cysteine proteases and metalloproteases. Ubiquitin specific protease 20 (USP20) is a member of the cysteine protease enzyme family and cloning of the gene was first described by Nagase et al. (1999). USP20 has been shown to specifically deubiquitylate and stabilise Hypoxia-inducible factor (HIF)-1α, increasing expression of HIF-1α targeted genes, such as vascular endothelial growth factor (VEGF) (Li et al., 2005). USP20 also deubiquitylates tumour necrosis receptor-associated factor 6 (TRAF6) and Tax and suppresses interleukin 1β (IL-1β) and Tax-induced NF-κB activation.
• Source: Insect cells
• Species: Human
• Tag: GST
• Form: 50 mM HEPES pH 7.5, 150 mM sodium chloride, 2 mM dithiothreitol, 10% glycerol
• Bio-activity: Deubiquitylase Enzyme Assay: The activity of GST-USP20 was validated by determining the increase in fluorescence measured as a result of the enzyme catalysed cleavage of the fluorogenic substrate Ubiquitin-Rhodamine110-Glycine generating Ubiquitin and Rhodamine110-Glycine. Incubation of the substrate in the presence or absence of GST-USP20 was compared confirming the deubiquitylating activity of GST-USP20.
