Mothers Against Decapentaplegic Homolog 2
Mothers against decapentaplegic homolog 2, also known as SMAD family member 2 or SMAD2, is a protein that in humans is encoded by the ''SMAD2'' gene. MAD homolog 2 belongs to the SMAD, a family of proteins similar to the gene products of the ''Drosophila'' gene ' mothers against decapentaplegic' (Mad) and the '' C. elegans'' gene Sma. SMAD proteins are signal transducers and transcriptional modulators that mediate multiple signaling pathways. Function SMAD2 mediates the signal of the transforming growth factor (TGF)-beta, and thus regulates multiple cellular processes, such as cell proliferation, apoptosis, and differentiation. This protein is recruited to the TGF-beta receptors through its interaction with the SMAD anchor for receptor activation (SARA) protein. In response to TGF-beta signal, this protein is phosphorylated by the TGF-beta receptors. The phosphorylation induces the dissociation of this protein with SARA and the association with the family member SMA ...

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called pep ...

ACVR1B
Activin receptor type-1B is a protein that in humans is encoded by the ''ACVR1B'' gene. ACVR1B or ALK-4 acts as a transducer of activin or activin-like ligands (e.g., inhibin) signals. Activin binds to either ACVR2A or ACVR2B and then forms a complex with ACVR1B. These go on to recruit the R-SMADs SMAD2 or SMAD3. ACVR1B also transduces signals of nodal, GDF-1, and Vg1; however, unlike activin, they require other coreceptor molecules such as the protein Cripto. Function Activins are dimeric growth and differentiation factors which belong to the transforming growth factor-beta (TGF-beta) superfamily of structurally related signaling proteins. Activins signal through a heteromeric complex of receptor serine kinases which include at least two type I (I and IB) and two type II (II and IIB) receptors. These receptors are all transmembrane proteins, composed of a ligand-binding extracellular domain with a cysteine-rich region, a transmembrane domain, and a cytoplasmic domain wi ...

Homeobox Protein TGIF1
Homeobox protein TGIF1 is a protein that, in humans, is encoded by the ''TGIF1'' gene. Alternative splicing has been observed at this locus and eight variants, encoding four distinct isoforms, are described. Function The protein encoded by this gene is a member of the three-amino acid loop extension (TALE) superclass of atypical homeodomains. TALE homeobox proteins are highly conserved transcription regulators. This particular homeodomain binds to a previously characterized retinoid X receptor responsive element from the cellular retinol-binding protein II promoter. In addition to its role in inhibiting 9-cis-retinoic acid-dependent RXR alpha transcription activation of the retinoic acid responsive element, the protein is an active transcriptional co-repressor of SMAD2 and may participate in the transmission of nuclear signals during development and in the adult. Clinical significance Mutations in this gene are associated with holoprosencephaly type 4, which is a structural ...

HDAC1
Histone deacetylase 1 (HDAC1) is an enzyme that in humans is encoded by the ''HDAC1'' gene. Function Histone acetylation and deacetylation, catalyzed by multisubunit complexes, play a key role in the regulation of eukaryotic gene expression. The protein encoded by this gene belongs to the histone deacetylase/acuc/apha family and is a component of the histone deacetylase complex. It also interacts with retinoblastoma tumor-suppressor protein and this complex is a key element in the control of cell proliferation and differentiation. Together with metastasis-associated protein-2 MTA2, it deacetylates p53 and modulates its effect on cell growth and apoptosis.

FOXH1
Forkhead box protein H1 is a protein that in humans is encoded by the ''FOXH1'' gene. Function FOXH1 encodes a human homolog of Xenopus forkhead activin signal transducer-1. FOXH1 protein binds SMAD2 and activates an activin response element via binding the DNA motif TGT(G/T)(T/G)ATT. ''FoxH1'' is a transcription factor that contains a conserved function in chordates. ''FoxH1'', acts in combination with other transcription factors, as a critical element of node formation in early embryo development. Specifically, ''FoxH''1 plays a role in anterior/posterior determination during gastrulation. By the third week of gestation, cells of the splanchnic mesoderm have migrated to the superior end of the embryo to form the cardiac crescent. The cardiac crescent forms two heart fields; primary heart field and the secondary heart field. At this point in development, the two heart fields fuse to form a primitive, single-chambered heart referred to as the primary myocardium. The secondary ...

EP300
Histone acetyltransferase p300 also known as p300 HAT or E1A-associated protein p300 (where E1A = adenovirus early region 1A) also known as EP300 or p300 is an enzyme that, in humans, is encoded by the ''EP300'' gene. It functions as histone acetyltransferase that regulates transcription of genes via chromatin remodeling by allowing histone proteins to wrap DNA less tightly. This enzyme plays an essential role in regulating cell growth and division, prompting cells to mature and assume specialized functions (differentiate), and preventing the growth of cancerous tumors. The p300 protein appears to be critical for normal development before and after birth. The EP300 gene is located on the long (q) arm of the human chromosome 22 at position 13.2. This gene encodes the adenovirus E1A-associated cellular p300 transcriptional co-activator protein. EP300 is closely related to another gene, CREB binding protein, which is found on human chromosome 16. Function p300 HAT funct ...

Mothers Against Drunk Driving
Mothers Against Drunk Driving (MADD) is a non-profit organization in the United States, Canada ( MADD Canada) and Brazil that seeks to stop driving with any amount of alcohol in the bloodstream, support those affected by drunk driving, prevent underage drinking, and strive for stricter impaired driving policy, whether that impairment is caused by alcohol or any other drug. The Irving, Texas-based organization was founded on September 5, 1980, in California by Candace Lightner after her 13-year-old daughter, Cari, was killed by a drunk driver. There is at least one MADD office in every state of the United States and at least one in each province of Canada. These offices offer victim services and many resources involving alcohol safety. MADD has claimed that drunk driving has been reduced by half since its founding. Positions According to MADD's website, "The mission of Mothers Against Drunk Driving is to end drunk driving, help fight drugged driving, support the victims of these vi ...

Decapentaplegic
''Decapentaplegic'' (''Dpp'') is a key morphogen involved in the development of the fruit fly ''Drosophila melanogaster'' and is the first validated secreted morphogen. It is known to be necessary for the correct patterning and development of the early ''Drosophila'' embryo and the fifteen imaginal discs, which are tissues that will become limbs and other organs and structures in the adult fly. It has also been suggested that ''Dpp'' plays a role in regulating the growth and size of tissues. Flies with mutations in decapentaplegic fail to form these structures correctly, hence the name (''decapenta''-, fifteen; -''plegic'', paralysis). ''Dpp'' is the ''Drosophila'' homolog of the vertebrate bone morphogenetic proteins (BMPs), which are members of the transforming growth factor beta superfamily, TGF-β superfamily, a class of proteins that are often associated with their own specific signaling pathway. Studies of ''Dpp'' in ''Drosophila'' have led to greater understanding of the func ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
