Application Abreviews Notes
ELISA 1/20000.
IHC-P 1/50 - 1/100.
WB 1/500 - 1/1000. Detects a band of approximately 52 kDa (predicted molecular weight: 52 kDa).


  • 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.
