Recombinant Human USP4, His-tagged

Cat.No.: USP4-183H
Product Overview: Recombinant human USP4 (amino acid residues 1-963), fused with N-terminal His, was expressed in E.coli.
Description: There are two main classes of DUB, cysteine proteases and metalloproteases. Ubiquitin carboxyl-terminal hydrolase 4 (Ubiquitin Specific Protease 4; USP4) is a member of the cysteine protease enzyme family and cloning of the human gene was first described by Gupta et al. (1993). In 1995, USP4 was identified as a proto-oncogene related to USP6, showing a consistently elevated gene expression level in small cell tumours and lung adenocarcinomas suggesting that it may have a possible causative role in neoplasia (Gray et al., 1995). USP4 has been implicated in a number of other processes, including protein quality control in the endoplasmatic reticulum and p53 and Wnt signalling. USP4 has also been reported to inhibit the kinase TAK1 that is ubiquitylated by the AKT regulator TRAF6 (Uras et al., 2012).
Source: E. coli
Species: Human
Tag: His
Form: 50 mM HEPES pH 7.5, 150 mM sodium chloride, 2 mM dithiothreitol, 10% glycerol
Bio-activity: Deubiquitylating Enzyme Assay: The activity of His-USP4 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 His-USP4 was compared confirming the deubiquitylating activity of His-USP4.
