General description

Mothers against decapentaplegic homolog 1 (UniProt: Q15797; also known as MAD homolog 1, Mothers against DPP homolog 1, JV4-1, Mad-related protein 1, SMAD family member 1, SMAD1, Smad1, hSMAD1, Transforming growth factor-beta-signaling protein 1, BSP-1) is encoded by the SMAD1 (also known as BSP1, MADH1, MADR1) gene (Gene ID: 4086) in human. Smad1 is a transcriptional modulator that is activated by BMP (bone morphogenetic protein) type 1 receptor kinase. Smad1 is a receptor-regulated Smad (R-Smad) that is found in a complex with Smad4 and YY1. Upon phosphorylation at the C-terminal by BMP type 1 receptor kinase it forms a trimer with another Smad1 and Smd4. The C-terminal phosphoserines of Smad1 are recognized by the Mad Homology 2 (MH2) domain of Smad4. The Smd1/Smad4 complex then translocates to the nucleus where Smad proteins bind to their cognate DNA binding sites with low affinity. This binding is further enhanced in the presence of transcriptional co-activators. Smad1 is ubiquitinated by Smad-specific E3 ubiquitin ligase SMURF1, leading to its degradation via proteasome Smad1 variants are associated with susceptibility to pulmonary hypertension that is characterized by plexiform lesions of proliferating endothelial cells in pulmonary arterioles.

Specificity

This rabbit polyclonal antibody detects Smad1 phosphorylated on Ser463 and Ser465. it targets an epitope within 8 amino acids surrounding Ser463 and Ser465.

Immunogen

Epitope: C-terminus
KLH-conjugated linear peptide corresponding to 8 amino acids surrounding pSer463/pSer465 from the C-terminus region of human Smad1.

Application

Anti-phospho-Smad1 (Ser463, Ser465), Cat. No. ABE2871, is a highly specific rabbit polyclonal antibody that targets Mothers against decapentaplegic homolog 1 (Smad1) and has been tested in Immunoprecipitation and Western Blotting.
Immunoprecipitation Analysis: A representative lot detected phospho-Smad1 (Ser463, Ser465) in constitutively active ALK6 version in 35S metabolic labeled COS cells (Persson, U., et. al. (1998). FEBS Lett. 434(1-2):83-7).
