Description : The chromosome 21 trisomy (Down syndrome) is the most frequent human birth defect, and an increase in USP25 gene dosage in Down syndrome patients could seriously disturb the balance between ubiquitylated and deubiquitylated substrates (Valero et al., 1999). Instability and allelic deletions of the 21q11-q21 region of the chromosome have been found in 13 of 34 squamous non-small cell lung carcinomas (Groet et al., 2000). USP25 is a target for SUMOylation, being more efficient with SUMO2/3. USP25 SUMOylation impairs binding to and hydrolysis of ubiquitin chains (Meulmeester et al., 2008). USP25 is deSUMOylated by SENP1 (Mohideen and Lima, 2008).
Source : E. coli
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-USP25 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-USP25 was compared confirming the deubiquitylating activity of GST-USP25.
