C-terminal Mad Homology 2 (MH2) domain; The MH2 domain is found in the SMAD (small mothers against decapentaplegic) family of proteins and is responsible for type I receptor interactions, phosphorylation-triggered homo- and hetero-oligomerization, and transactivation. It is negatively regulated by the N-terminal MH1 domain which prevents it from forming a complex with SMAD4. The MH2 domain is multifunctional and provides SMADs with their specificity and selectivity, as well as transcriptional activity. Several transcriptional co-activators and repressors have also been reported to regulate SMAD signaling by interacting with the MH2 domain. Mutations in the MH2 domains of SMAD2 and especially SMAD4 have been detected in colorectal and other human cancers.

 41-162 3.86e-85

N-terminal Mad Homology 1 (MH1) domain in SMAD1, SMAD5 and SMAD9 (also known as SMAD8); The MH1 is a small DNA-binding domain present in SMAD (small mothers against decapentaplegic) family of proteins, which are signal transducers and transcriptional modulators that mediate multiple signaling pathways. MH1 binds to the DNA major groove in an unusual manner via a beta hairpin structure. It negatively regulates the functions of the MH2 domain, the C-terminal domain of SMAD. This MH1 domain is found in SMAD1, SMAD5 and SMAD9, all closely related receptor regulated SMADs (R-SMADs). SMAD1 plays an essential role in bone development and postnatal bone formation through activation by bone morphogenetic protein (BMP) type 1 receptor kinase. SMAD5 is involved in bone morphogenetic proteins (BMP) signal modulation and may also play a role in the pathway involving inhibition of hematopoietic progenitor cells by TGF-beta. SMAD9 mediates the differentiation of mesenchymal stem cells (MSCs) into tendon-like cells by inhibiting the osteogenic pathway.

 260-432 4.33e-99

MH2 domain; This is the MH2 (MAD homology 2) domain found at the carboxy terminus of MAD related proteins such as Smads. This domain is separated from the MH1 domain by a non-conserved linker region. The MH2 domain mediates interaction with a wide variety of proteins and provides specificity and selectivity to Smad function and also is critical for mediating interactions in Smad oligomers. Unlike MH1, MH2 does not bind DNA. The well-studied MH2 domain of Smad4 is composed of five alpha helices and three loops enclosing a beta sandwich. Smads are involved in the propagation of TGF-beta signals by direct association with the TGF-beta receptor kinase which phosphorylates the last two Ser of a conserved 'SSXS' motif located at the C-terminus of MH2.

MH1 domain; The MH1 (MAD homology 1) domain is found at the amino terminus of MAD related proteins such as Smads. This domain is separated from the MH2 domain by a non-conserved linker region. The crystal structure of the MH1 domain shows that a highly conserved 11 residue beta hairpin is used to bind the DNA consensus sequence GNCN in the major groove, shown to be vital for the transcriptional activation of target genes. Not all examples of MH1 can bind to DNA however. Smad2 cannot bind DNA and has a large insertion within the hairpin that presumably abolishes DNA binding. A basic helix (H2) in MH1 with the nuclear localization signal KKLKK has been shown to be essential for Smad3 nuclear import. Smads also use the MH1 domain to interact with transcription factors such as Jun, TFE3, Sp1, and Runx.

The MH2 domain is responsible for type I receptor interaction, phosphorylation-triggered homo- and hetero-oligomerization, and transactivation. It is negatively regulated by the N-terminal MH1 domain. Receptor regulated SMADs (R-SMADs) include SMAD1, SMAD2, SMAD3, SMAD5 and SMAD9. SMAD1 plays an essential role in bone development and postnatal bone formation through activation by bone morphogenetic protein (BMP) type 1 receptor kinase. SMAD2 regulates multiple cellular processes, such as cell proliferation, apoptosis and differentiation, while SMAD3 modulates signals of activin and TGF-beta. SMAD5 is involved in BMP signal modulation, possibly playing a role in the pathway involving inhibition of hematopoietic progenitor cells by TGF-beta. SMAD9 (also known as SMAD8) can mediate the differentiation of mesenchymal stem cells into tendon-like cells by inhibiting the osteogenic pathway.

It is negatively regulated by the N-terminal MH1 domain which prevents it from forming a complex with SMAD4. The MH2 domain is multifunctional and provides SMADs with their specificity and selectivity, as well as transcriptional activity. Several transcriptional co-activators and repressors have also been reported to regulate SMAD signaling by interacting with the MH2 domain. Mutations in the MH2 domains of SMAD2 and especially SMAD4 have been detected in colorectal and other human cancers.

MH2 domain; This is the MH2 (MAD homology 2) domain found at the carboxy terminus of MAD related proteins such as Smads. This domain is separated from the MH1 domain by a non-conserved linker region. The MH2 domain mediates interaction with a wide variety of proteins and provides specificity and selectivity to Smad function and also is critical for mediating interactions in Smad oligomers. Unlike MH1, MH2 does not bind DNA. The well-studied MH2 domain of Smad4 is composed of five alpha helices and three loops enclosing a beta sandwich. Smads are involved in the propagation of TGF-beta signals by direct association with the TGF-beta receptor kinase which phosphorylates the last two Ser of a conserved 'SSXS' motif located at the C-terminus of MH2.

N-terminal Mad Homology 1 (MH1) domain in SMAD1, SMAD5 and SMAD9 (also known as SMAD8); The MH1 is a small DNA-binding domain present in SMAD (small mothers against decapentaplegic) family of proteins, which are signal transducers and transcriptional modulators that mediate multiple signaling pathways. MH1 binds to the DNA major groove in an unusual manner via a beta hairpin structure. It negatively regulates the functions of the MH2 domain, the C-terminal domain of SMAD. This MH1 domain is found in SMAD1, SMAD5 and SMAD9, all closely related receptor regulated SMADs (R-SMADs). SMAD1 plays an essential role in bone development and postnatal bone formation through activation by bone morphogenetic protein (BMP) type 1 receptor kinase. SMAD5 is involved in bone morphogenetic proteins (BMP) signal modulation and may also play a role in the pathway involving inhibition of hematopoietic progenitor cells by TGF-beta.

This MH1 is found in SMAD2 as well as SMAD3. SMAD2 mediates the signal of the transforming growth factor (TGF)-beta, and thereby regulates multiple cellular processes, such as cell proliferation, apoptosis, and differentiation. It plays a role in the transmission of extracellular signals from ligands of the TGF-beta superfamily growth factors into the cell nucleus. SMAD3 modulates signals of activin and TGF-beta. It binds SMAD4, enabling its transmigration into the nucleus where it forms complexes with other proteins and acts as a transcription factor. Increased SMAD3 activity has been implicated in the pathogenesis of scleroderma.

N-terminal Mad Homology 1 (MH1) domain; The MH1 is a small DNA-binding domain present in SMAD (small mothers against decapentaplegic) family of proteins, which are signal transducers and transcriptional modulators that mediate multiple signaling pathways. MH1 binds to the DNA major groove in an unusual manner via a beta hairpin structure. It negatively regulates the functions of the MH2 domain, the C-terminal domain of SMAD. Receptor-regulated SMAD proteins (R-SMADs, including SMAD1, SMAD2, SMAD3, SMAD5, and SMAD9) are activated by phosphorylation by transforming growth factor (TGF)-beta type I receptors. The active R-SMAD associates with a common mediator SMAD (Co-SMAD or SMAD4) and other cofactors, which together translocate to the nucleus to regulate gene expression. The inhibitory or antagonistic SMADs (I-SMADs, including SMAD6 and SMAD7) negatively regulate TGF-beta signaling by competing with R-SMADs for type I receptor or Co-SMADs. MH1 domains of R-SMAD and SMAD4 contain a nuclear localization signal as well as DNA-binding activity. The activated R-SMAD/SMAD4 complex then binds with very low affinity to a DNA sequence CAGAC called SMAD-binding element (SBE) via the MH1 domain.

C-terminal Mad Homology 2 (MH2) domain in SMAD4; The MH2 domain is located at the C-terminus of the SMAD (small mothers against decapentaplegic) family of proteins, which are signal transducers and transcriptional modulators that mediate multiple signaling pathways. The MH2 domain is responsible for type I receptor interaction, phosphorylation-triggered homo- and hetero-oligomerization, and transactivation. It is negatively regulated by the N-terminal MH1 domain. SMAD4, which belongs to the Dwarfin family of proteins, is involved in many cell functions such as differentiation, apoptosis, gastrulation, embryonic development and the cell cycle. SMAD4 binds receptor regulated SMADs (R-SMADs) such as SMAD1 or SMAD2, and forms an oligomeric complex that binds to DNA and serves as a transcription factor. SMAD4 is often mutated in several cancers, such as multiploid colorectal cancer, cervical cancer and pancreatic carcinoma, as well as in juvenile polyposis syndrome.

MH1 domain; The MH1 (MAD homology 1) domain is found at the amino terminus of MAD related proteins such as Smads. This domain is separated from the MH2 domain by a non-conserved linker region. The crystal structure of the MH1 domain shows that a highly conserved 11 residue beta hairpin is used to bind the DNA consensus sequence GNCN in the major groove, shown to be vital for the transcriptional activation of target genes. Not all examples of MH1 can bind to DNA however. Smad2 cannot bind DNA and has a large insertion within the hairpin that presumably abolishes DNA binding. A basic helix (H2) in MH1 with the nuclear localization signal KKLKK has been shown to be essential for Smad3 nuclear import. Smads also use the MH1 domain to interact with transcription factors such as Jun, TFE3, Sp1, and Runx.
