Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 35 kDa.
IHC-P 1/500 - 1/1000. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. (Heat to 98°C allow to cool for 10-20 min).
ICC/IF 1/500 - 1/1000.
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function

      Metalloprotease component of the 26S proteasome that specifically cleaves 'Lys-63'-linked polyubiquitin chains. The 26S proteasome is involved in the ATP-dependent degradation of ubiquitinated proteins. The function of the 'Lys-63'-specific deubiquitination of the proteasome is unclear.
    • Tissue specificity

      Widely expressed. Highest levels in heart and skeletal muscle.
    • Sequence similarities

      Belongs to the peptidase M67A family. PSMD14 subfamily.
      Contains 1 MPN (JAB/Mov34) domain.
