Active Recombinant Human STAMBP, GST-tagged

• Cat.No.: STAMBP-167H
• Product Overview: Recombinant human STAMBP (amino acid residues 252-424), fused with N-terminal GST, was expressed in E.coli.

Specification

• Description: AMSH is a member of the JAB1/MPN/Mov34 metalloenzyme (JAMM) family and cloning of the human gene was first described by Tanaka et al. (1999). AMSH and AMSH-LP share 54% identity and 75% sequence similarity in their JAMM domain. It is known that both proteins act as regulators of free ubiquitin in the cell, bind clathrin, and contain a putative nuclear localization signal and a microtubule interacting and transport (MIT) domain. AMSH also contains a Src homology 3 (SH3) domain, facilitating its interaction with signal transducing adaptor molecule (STAM), while this functional SH3-binding motif is lost in AMSH-LP (Davies, et al., 2011).
• 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: The activity of GST-AMSH CD(252-424) was validated by the monitoring of mono-ubiquitin generation as a result of the enzyme catalysed cleavage of K63-linked di-ubiquitin. Incubation of the substrate in the presence or absence of GST-AMSH CD(252-424) was compared confirming the deubiquitylating activity of GST-AMSH CD(252-424).
