Component of the heterotrimeric SMAD2\/SMAD3-SMAD4 complex that forms in the nucleus and is required for the TGF-mediated signaling. 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. 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. 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. 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 (By similarity).\u003c\/p\u003e","brand":"BT LAB","offers":[{"title":"Default Title","offer_id":56592918020469,"sku":"BT-E1260Ra-96T","price":370.98,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0843\/2671\/1640\/files\/ELISA_Kit_main_1.jpg?v=1766393459","url":"https:\/\/www.labcart.com\/de\/products\/rat-mothers-against-decapentaplegic-homolog-4-smad4-elisa-kit-96t","provider":"LabCart Life Science","version":"1.0","type":"link"}
