  2. SMAD (protein) - Wikipedia

    en.wikipedia.org/wiki/SMAD_(protein)

    This phenomenon is present in the epithelial cells of many organs, and is regulated in part by the Smad signaling pathway. The precise mechanism of control differs slightly between cell types. One mechanism by which Smads facilitate TGF-β induced cytostasis is by downregulating Myc , which is a transcription factor that promotes cell growth.

  3. Bone morphogenetic protein - Wikipedia

    en.wikipedia.org/wiki/Bone_morphogenetic_protein

    Bone morphogenetic proteins (BMPs) are a group of growth factors also known as cytokines and as metabologens. [1] Professor Marshall Urist and Professor Hari Reddi discovered their ability to induce the formation of bone and cartilage, BMPs are now considered to constitute a group of pivotal morphogenetic signals, orchestrating tissue architecture throughout the body.

    en.wikipedia.org/wiki/Mothers_against...

    MED15 is a mediator molecule that promotes the activity of the TGF-β/SMAD signaling. The deficiency of this molecule attenuates the activity of the TGF-β/SMAD signaling pathway over the genes required for induction of epithelial-mesenchymal transition. The action of MED15 is related with the phosphorylation of SMAD2/3 complex.

  5. TGF beta signaling pathway - Wikipedia

    en.wikipedia.org/wiki/TGF_beta_signaling_pathway

    SARA orients the R-SMAD such that serine residue on its C-terminus faces the catalytic region of the Type I receptor. The Type I receptor phosphorylates the serine residue of the R-SMAD. Phosphorylation induces a conformational change in the MH2 domain of the R-SMAD and its subsequent dissociation from the receptor complex and SARA. [10]

    Type 1 contains a glycine-serine-rich domain to be phosphorylated by type 2 kinase domain, initiating the signaling transduction pathway of the SMAD signaling cascade. [3] The wrist epitope motif on BMP-2 has a high-affinity binding site for BMPR-IA. The knuckle epitope motif on BMP-2 has a low-affinity binding site for BMPR-II. [4]

  7. Bone morphogenetic protein 4 - Wikipedia

    en.wikipedia.org/wiki/Bone_morphogenetic_protein_4

    BMP4 is also known to activate the ERK, JNK and p38 MAPK signalling pathways whilst have been found to act independently of Smad signaling pathways, are mostly active in conjunction with Smad. [32] The activation of the ERK and JNK pathways acts to phosphorylate Smad and therefore regulate its activation.

  8. Mothers against decapentaplegic homolog 1 - Wikipedia

    en.wikipedia.org/wiki/Mothers_against...

    SMAD proteins are signal transducers and transcriptional modulators that mediate multiple signaling pathways. This protein mediates the signals of the bone morphogenetic proteins (BMPs), which are involved in a range of biological activities including cell growth, apoptosis , morphogenesis , development and immune responses.

  9. R-SMAD - Wikipedia

    en.wikipedia.org/wiki/R-SMAD

    R-SMADS include SMAD2 and SMAD3 from the TGF-β/Activin/Nodal branch, and SMAD1, SMAD5 and SMAD9 from the BMP/GDP branch of TGF-β signaling. [ 1 ] In response to signals by the TGF-β superfamily of ligands these proteins associate with receptor kinases and are phosphorylated at an SSXS motif at their extreme C-terminus .
