Interpolated concentrations of native SMAD4 in human colon tissue homogenate extract samples based on a 500 μg/mL extract load.

The concentrations of SMAD4 were measured in duplicate and interpolated from the SMAD4 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean SMAD4 concentration was determined to be 1,842.46 pg/mL in colon homogenate extract.

제품 세부 정보

Human SMAD4 ELISA Kit (ab253211) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of SMAD4 protein in cell lysate. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human SMAD4 with 52.31 pg/ml sensitivity.

SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:

- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips

A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

SMAD4 is a transcription factor involved in TGF-B signal transduction. SMAD4 is highly conserved across metazoans and is a part of the SMAD family of transcription factors.

Smad4 also known as DPC4 or MADH4 is a central protein in the TGF-beta signaling pathway with a molecular mass of approximately 60 kDa. It acts as a signal transducer that facilitates communication from the cell surface to the nucleus. Smad4 is broadly expressed in various tissues playing an important role in the regulation of cellular processes. It forms a complex with receptor-regulated Smads (R-Smads) to translocate to the nucleus where it influences gene transcription.

Biological function summary

Smad4 influences cell proliferation differentiation and apoptosis by mediating signals from TGF-beta cytokines. It is part of the Smad protein family acting as a transcriptional controller. Upon TGF-beta receptor activation Smad4 forms complexes with Smad2 and Smad3 translocating to the nucleus to regulate genes imperative for cellular homeostasis. Its role in cell cycle regulation underlines its contribution to normal cellular functions and its potential involvement in disorders.

Pathways

Smad4 operates within the TGF-beta pathway linking extracellular signals to nuclear transcription alterations. It participates in the regulation of epithelial-mesenchymal transition (EMT) a process important for development and tumor progression. In these pathways Smad4 interacts closely with Smad2 and Smad3 orchestrating various cellular responses to external stimuli through transcriptional management.

Smad4 is highly related to cancer and juvenile polyposis syndrome. Mutations or deletions in Smad4 disrupt its function contributing to the progression of pancreatic cancer and colorectal cancer among others. Within these contexts Smad4 connects strongly to other proteins like p21 and cyclin-dependent kinase inhibitors which are important in cell cycle arrest and impede tumor growth.

타겟 정보

In muscle physiology, plays a central role in the balance between atrophy and hypertrophy. When recruited by MSTN, promotes atrophy response via phosphorylated SMAD2/4. MSTN decrease causes SMAD4 release and subsequent recruitment by the BMP pathway to promote hypertrophy via phosphorylated SMAD1/5/8. Acts synergistically with SMAD1 and YY1 in bone morphogenetic protein (BMP)-mediated cardiac-specific gene expression. Binds to SMAD binding elements (SBEs) (5'-GTCT/AGAC-3') within BMP response element (BMPRE) of cardiac activating regions (By similarity). Common SMAD (co-SMAD) is the coactivator and mediator of signal transduction by TGF-beta (transforming growth factor). Component of the heterotrimeric SMAD2/SMAD3-SMAD4 complex that forms in the nucleus and is required for the TGF-mediated signaling (PubMed : 25514493). Promotes binding of the SMAD2/SMAD4/FAST-1 complex to DNA and provides an activation function required for SMAD1 or SMAD2 to stimulate transcription. Component of the multimeric SMAD3/SMAD4/JUN/FOS complex which forms at the AP1 promoter site; required for synergistic transcriptional activity in response to TGF-beta. May act as a tumor suppressor. Positively regulates PDPK1 kinase activity by stimulating its dissociation from the 14-3-3 protein YWHAQ which acts as a negative regulator.
