Smad1 (P457) pAb detects endogenous levels of Smad1 protein.
Applications:
WB, IHC
Reactivity:
Human, Mouse, Rat
Immunogen:
Synthetic peptide, corresponding to amino acids 424-478 of Human Smad1.
Host:
Rabbit
Clonality:
Polyclonal
Conjugate:
Unconjugated
Molecular Weight:
~ 60 kDa
Purity:
The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).
Product Form:
1 mg/ml in Phosphate buffered saline (PBS) with 0.05% sodium azide, approx. pH 7.2.
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. May act synergistically with SMAD4 and YY1 in bone morphogenetic protein (BMP)-mediated cardiac-specific gene expression.
Tissue Specificity:
Ubiquitous. Highest expression seen in the heart and skeletal muscle.
Sequence Similarities:
Belongs to the dwarfin/SMAD family.
Post-Translational Modification:
Phosphorylation of the C-terminal SVS motif by BMP type 1 receptor kinase activates SMAD1 by promoting dissociation from the receptor and trimerization with SMAD4.
Cellular Location:
Cytoplasm. Nucleus.
Cytoplasmic in the absence of ligand. Migrates to the nucleus when complexed with SMAD4 (PubMed:15647271). Co-localizes with LEMD3 at the nucleus inner membrane (PubMed:15647271).
