General description

Members of the Smad family of signal transduction molecules are components of a critical intracellular pathway that transmits TGF-β signals from the cell surface into the nucleus. Three distinct classes of Smads have been defined: the receptor-regulated Smads (R-Smads), which include Smad1, 2, 3, 5 and 8, the common-mediator Smad (co-Smad), Smad4, and the antagonistic or inhibitory Smads (I-Smads), Smad6 and 7. Once in the nucleus, Smads can target a variety of DNA binding proteins to regulate transcriptional responses. Following stimulation by TGF-β, Smad2 and Smad3 become phosphorylated at their carboxyl termini (Ser465 and 467 on Smad2; Ser423 and 425 on Smad3) by TGF-β Receptor I. Phosphorylated Smad 2/3 can complex with Smad4, translocate to the nucleus and regulate gene expression.

Specificity

Detects phosphorylated Smad3 (Ser423 and Ser425).

Immunogen

Epitope: Phosphorylated Ser423/425
KLH-conjugated, synthetic phospho-peptide corresponding to residues surrounding Ser423/425 of human Smad3.

Application

Anti-phospho-Smad3 (Ser423/425) Antibody is a Rabbit Polyclonal Antibody for detection of phospho-Smad3 (Ser423/425) also known as MAD Mothers against DPP homolog 3 & has been validated in WB.
Research Category
Signaling

Quality

Evaluated by western blot on untreated and UV-treated AKR-2B cell lysate.

The TGF-β1 transcription factor SMAD3 is epigenetically repressed in tumour-associated fibroblasts (TAFs) from lung squamous cell carcinoma (SCC) but not adenocarcinoma (ADC) patients, which elicits a compensatory increase in SMAD2 that renders SCC-TAFs less fibrotic. Here we examined the effects
