|Calculated MW||52260 Da|
|Other Names||Mothers against decapentaplegic homolog 1, MAD homolog 1, Mothers against DPP homolog 1, JV4-1, Mad-related protein 1, SMAD family member 1, SMAD 1, Smad1, hSMAD1, Transforming growth factor-beta-signaling protein 1, BSP-1, SMAD1, BSP1, MADH1, MADR1|
|Target/Specificity||A synthetic peptide corresponding to residues in human Smad1 was used as immunogen.|
|Format||50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Smad1 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Synonyms||BSP1, MADH1, MADR1|
|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. May act synergistically with SMAD4 and YY1 in bone morphogenetic protein (BMP)-mediated cardiac-specific gene expression.|
|Cellular Location||Cytoplasm. Nucleus. Note=Cytoplasmic in the absence of ligand. Migrates to the nucleus when complexed with SMAD4. Co-localizes with LEMD3 at the nucleus inner membrane|
|Tissue Location||Ubiquitous. Highest expression seen in the heart and skeletal muscle|

Smad 1 is a member of the Mothers Against Dpp (MAD)-related family of proteins. So far, eight Smads have been identified and can be divided in 3 subgroups based on their structure and function; pathway-restricted, common mediator and inhibitory. Smad 1, 5 and 8 serve as pathway-restricted Smads for the bone morphogenetic proteins (BMPs) signaling pathway (1). Smad 1 is involved in cell growth, apoptosis, morphogenesis, development and immune response (2). After phosphorylation by the BMP type 1 receptor kinase Smad1 and co-Smad4 form a heteromeric complex and translocate to the nucleus to regulate transcription of target genes (3).
