Product Specifications

Source

Spodoptera frugiperda, Sf 21 (baculovirus)-derived human AMSH/STAMBP protein

Purity

>85%, by SDS-PAGE under reducing conditions and visualized by Colloidal Coomassie® Blue stain.

Predicted Molecular Mass

48 kDa

Activity

Recombinant Human AMSH is a Ubiquitin-specific deconjugating enzyme. Reaction conditions will need to be optimized for each specific application. We recommend an initial Recombinant Human AMSH concentration of 100-500 nM.  AMSH activity is partially or fully inhibited by DTT at concentrations above 1 mM.

Background: AMSH/STAMBP

AMSH (STAM binding protein) is a zinc metalloprotease belonging to the JAMM (JAB1/MPN/Mov34) family of deubiquitinating enzymes (DUBs). This enzyme functions at the endosome, where it is involved in the sorting of various cell-surface receptors to lysozomes. AMSH cleaves K63-linked but not K48-linked polyubiquitin chains, and the in vitro activity of AMSH is greatly increased in the presence of STAM protein. This recombinant protein is full-length.
