Chain A, Mothers against decapentaplegic homolog 2

Protein Classification

mothers against decapentaplegic homolog( domain architecture ID 10181107)

mothers against decapentaplegic homolog such as SMAD1, SMAD5 and SMAD9 (also known as SMAD8); 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

 7-197 1.25e-158

C-terminal Mad Homology 2 (MH2) domain in SMAD2 and SMAD3; 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. SMAD2 and SMAD3 are receptor regulated SMADs (R-SMADs). SMAD2 regulates multiple cellular processes, such as cell proliferation, apoptosis and differentiation, while SMAD3 modulates signals of activin and TGF-beta.

 14-184 3.45e-105

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.

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.

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.

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.

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.

C-terminal Mad Homology 2 (MH2) domain in Inhibitory SMADs; 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, which prevents it from forming a complex with SMAD4. SMAD6 and SMAD7 are inhibitory SMADs (I-SMADs) that function as negative regulators of signaling mediated by the TGF-beta superfamily. SMAD6 specifically inhibits bone morphogenetic protein (BMP) type I receptor mediated signaling, while SMAD7 enhances muscle differentiation and is often associated with cancer, tissue fibrosis and inflammatory diseases.

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, which prevents it from forming a complex with SMAD4. SMAD6, an inhibitory or antagonistic SMAD (I-SMAD), acts as a negative regulator of signaling mediated by the TGF-beta superfamily of ligands, by competing with SMAD4 and preventing the transcription of SMAD4's gene products. SMAD6 specifically inhibits bone morphogenetic protein (BMP) type I receptor mediated signaling. SMAD6 and SMAD7 act as critical mediators for effective TGF-beta I-mediated suppression of Interleukin-1/Toll-like receptor (IL-1R/TLR) signaling through simultaneous binding to Pellino-1, an adaptor protein of interleukin-1 receptor associated kinase 1 (IRAK1), via their MH2 domains.

C-terminal Mad Homology 2 (MH2) domain in SMAD7; 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, which prevents it from forming a complex with SMAD4. SMAD7, an inhibitory or antagonistic SMAD (I-SMAD), acts as a negative regulator of signaling mediated by the TGF-beta superfamily of ligands, by blocking TGF-beta type 1 and activin association with the receptor as well as access to SMAD2. SMAD7 enhances muscle differentiation, playing pivotal roles in embryonic development and adult homoeostasis. SMAD7 and SMAD6 act as critical mediators for effective TGF-beta I-mediated suppression of Interleukin-1/Toll-like receptor (IL-1R/TLR) signaling through simultaneous binding to Pellino-1, an adaptor protein of interleukin-1 receptor associated kinase 1(IRAK1), via their MH2 domains. Altered expression of SMAD7 is often associated with cancer, tissue fibrosis and inflammatory diseases.
