    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • FunctionTranscriptional 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 specificityUbiquitous. Highest expression seen in the heart and skeletal muscle.
    • Sequence similaritiesBelongs to the dwarfin/SMAD family.
      Contains 1 MH1 (MAD homology 1) domain.
      Contains 1 MH2 (MAD homology 2) domain.
    • Post-translational
      Phosphorylated on serine by BMP type 1 receptor kinase.
      Ubiquitin-mediated proteolysis by SMAD-specific E3 ubiquitin ligase SMURF1.
    • Cellular localizationCytoplasm. Nucleus. Cytoplasmic in the absence of ligand. Migrates to the nucleus when complexed with SMAD4. Co-localizes with LEMD3 at the nucleus inner membrane.
