|Calculated MW||52713 Da|
|Application & Usage||Western blotting (0.5-4 µg/ml). However, the optimal concentrations should be determined individually. The antibody recognizes ~50-60 kDa Smad1 from samples of human, mouse, and rat origins. Reactivity to other species has not been tested.|
|Other Names||MADR1 , JV41 , JV4-1 , GARS , CMT2D , hSMAD1 , HMN5 , MADH1 , BSP-1 , BSP1|
|Formulation||100 µg (0.5 mg/ml) affinity purified rabbit polyclonal antibody in phosphate-buffered saline (PBS) containing 30% glycerol, 0.5% BSA, and 0.01% thimerosal.|
|Handling||The antibody solution should be gently mixed before use.|
|Reconstitution & Storage||-20 °C|
|Precautions||Smad1 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||Transcriptional modulator activated by BMP (bone morphogenetic proteins) type 1 receptor kinase. SMAD1 is a receptor-regulated SMAD (R-SMAD). Has been shown to be also activated by TGF-beta (transforming growth factor) type I receptor kinase in rat intestinal epithelial cells (IEC 4-1). 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 (By similarity).|
|Cellular Location||Cytoplasm. Nucleus. Note=In the cytoplasm in the absence of ligand Migration to the nucleus when complexed with SMAD4. Colocalizes with LEMD3 at the nucleus inner membrane (By similarity)|
|Tissue Location||Ubiquitous; present in liver, lung, stomach and spleen with lower level in heart, testes and skeletal muscle|

Provided below are standard protocols that you may find useful for product applications.
Smad proteins, the mammalian homologs of the Drosophila Mothers against dpp (Mad), have been implicated as downstream effectors of TGFβ/BMP signaling. Smad1, Smad5, and Smad8 are effectors of BMP2 and BMP4 function while Smad2 and Smad3 are involved in TGF-β and activin-mediated growth modulation. Smad4 has been shown to mediate all of the above activities thro µgh interaction with various Smad family members. Smad6 and Smad7 regulate the response to activin/TGFβ signaling by interfering with TGFβ-mediated phosphorylation of other Smad family members.
