The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF 1/100 - 1/250.
WB 1/500 - 1/2000. Detects a band of approximately 58 kDa (predicted molecular weight: 52 kDa).
  • Application notes
    Is unsuitable for Flow Cyt,IHC or IP.
  • Target

    • Function
      Transcriptional modulator activated by BMP (bone morphogenetic proteins) type 1 receptor kinase. SMAD1 is a receptor-regulated SMAD (R-SMAD). SMAD1/OAZ1/PSMB4 complex mediates the degradation of the CREBBP/EP300 repressor SNIP1.
    • Tissue specificity
      Ubiquitous. Highest expression seen in the heart and skeletal muscle.
    • Sequence similarities
      Belongs to the dwarfin/SMAD family.
      Contains 1 MH1 (MAD homology 1) domain.
      Contains 1 MH2 (MAD homology 2) domain.
    • Post-translational
      modifications
      Phosphorylated on serine by BMP type 1 receptor kinase.
      Ubiquitin-mediated proteolysis by SMAD-specific E3 ubiquitin ligase SMURF1.
    • Cellular localization
      Cytoplasm. Nucleus. Cytoplasmic in the absence of ligand. Migrates to the nucleus when complexed with SMAD4. Co-localizes with LEMD3 at the nucleus inner membrane.
