Descrizione generale

Human USP8 (Ubiquitin-Specific Protease 8) or UBPY, amino-acids 2-1118 (end) with an N-terminal FLAG-tag, expressed in a baculovirus-infected Sf9 cell expression system.

Applicazioni

Useful for the study of enzyme kinetics, screening inhibitors, and selectivity profiling.

Azioni biochim/fisiol

Expression of ubiquitin-specific protease 8 (USP8) in mice is critical for proper expression and stability of several growth factor receptors including epidermal growth factor receptor. However, USP8 was shown to degrade chemokine receptor 4.

The ubiquitin pathway has been implicated in the regulation of the abundance of proteins that control cell growth and proliferation. We have identified and characterized a novel human ubiquitin isopeptidase, UBPY, which both as a recombinant protein and upon immunoprecipitation

Ligand-activated receptor tyrosine kinases undergo endocytosis and are transported via endosomes to lysosomes for degradation. This "receptor down-regulation" process is crucial to terminate the cell proliferation signals produced by activated receptors. During the process, ubiquitination of the receptors serves as

Posttranslational modification by ubiquitin controls multiple cellular functions and is counteracted by the activities of deubiquitinating enzymes. UBPy (USP8) is a growth-regulated ubiquitin isopeptidase that interacts with the HRS-STAM complex. Using Cre-loxP-mediated gene targeting in mice, we show that lack
