• Purity

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

• Activity

  Reaction conditions will need to be optimized for each specific application. We recommend an initial recombinant human USP15 concentration of 5-20 nM when using Ubiquitin-AMC or Ubiquitin-Rh110 substrates (U-550, U-555).

Background: USP15

Ubiquitin carboxyl-terminal hydrolase 15 (USP15) is a specialized cysteine protease with a predicted molecular weight of 112 kDa.  USP15 is a member of the peptidase C19 family and the human protein shares 98% amino acid sequence identity with its mouse ortholog.  USP15 is a regulator of the TGF beta signaling pathway, where it may promote signaling strength by deubiquitination of SMAD proteins and/or the TGF beta R1.  Other reported targets of USP15 include histone H2B, NF kappa BI alpha, MDM2 and human papillomavirus type 16 E6 protein.
