TGFBR1
Transforming growth factor beta receptor I (activin A receptor type II-like kinase, 53kDa) is a membrane-bound TGF beta receptor protein of the TGF-beta receptor family The transforming growth factor beta (TGFβ) receptors are a family of serine/threonine kinase receptors involved in TGF beta signaling pathway. These receptors bind growth factor and cytokine signaling proteins in the TGF-beta family such ... for the Transforming growth factor beta, TGF beta superfamily of signaling ligands. ''TGFBR1'' is its human gene. Function The protein encoded by this gene forms a heteromeric complex with TGF beta receptor 2, type II TGF-β receptors when bound to TGF-β, transducing the TGF-β signal from the cell surface to the cytoplasm. The encoded protein is a serine/threonine protein kinase. Mutations in this gene have been associated with Loeys–Dietz syndrome, Loeys–Dietz aortic aneurysm syndrome (LDS, LDAS). Interactions TGF beta receptor 1 has been shown to Prote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loeys–Dietz Syndrome
Loeys–Dietz syndrome (LDS) is an autosomal dominant genetic connective tissue disorder. It has features similar to Marfan syndrome and Ehlers–Danlos syndrome. The disorder is marked by aneurysms in the aorta, often in children, and the aorta may also undergo sudden dissection in the weakened layers of the wall of the aorta. Aneurysms and dissections also can occur in arteries other than the aorta. Because aneurysms in children tend to rupture early, children are at greater risk for dying if the syndrome is not identified. Surgery to repair aortic aneurysms is essential for treatment. There are five types of the syndrome, labelled types I through V, which are distinguished by their genetic cause. Type 1, Type 2, Type 3, Type 4 and Type 5 are caused by mutations in ''TGFBR1'', ''TGFBR2'', ''SMAD3'', '' TGFB2'', and '' TGFB3'' respectively. These five genes encoding transforming growth factors play a role in cell signaling that promotes growth and development of the body's t ...

TGF Beta Receptor
Transforming growth factor beta (TGFβ) receptors are single pass serine/threonine kinase receptors that belong to TGFβ receptor family. They exist in several different isoforms that can be homo- or heterodimeric. (free full text) The number of characterized ligands in the TGFβ superfamily far exceeds the number of known receptors, suggesting the promiscuity that exists between the ligand and receptor interactions. TGFβ is a growth factor and cytokine involved in paracrine signalling and can be found in many different tissue types, including brain, heart, kidney, liver, bone, and testes. Over-expression of TGFβ can induce renal fibrosis, causing kidney disease, as well as diabetes, and ultimately end-stage renal disease. Recent developments have found that, using certain types of protein antagonists against TGFβ receptors, can halt and in some cases reverse the effects of renal fibrosis. Three TGFβ superfamily receptors specific for TGFβ, the TGFβ receptors, can be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heat Shock Protein 90kDa Alpha (cytosolic), Member A1
Heat shock protein HSP 90-alpha is a protein that in humans is encoded by the ''HSP90AA1'' gene. Function The gene, HSP90AA1, encodes the human stress-inducible 90-kDa heat shock protein alpha (Hsp90A). Complemented by the constitutively expressed paralog Hsp90B which shares over 85% amino acid sequence identity, Hsp90A expression is initiated when a cell experiences proteotoxic stress. Once expressed Hsp90A dimers operate as molecular chaperones that bind and fold other proteins into their functional 3-dimensional structures. This molecular chaperoning ability of Hsp90A is driven by a cycle of structural rearrangements fueled by ATP hydrolysis. Current research on Hsp90A focuses in its role as a drug target due to its interaction with a large number of tumor promoting proteins and its role in cellular stress adaptation. Gene structure Human HSP90AA1 is encoded on the complement strand of Chromosome 14q32.33 and spans over 59 kbp. Several pseudogenes of HSP90AA1 exist ...

Mothers Against Decapentaplegic Homolog 7
Mothers against decapentaplegic homolog 7 or SMAD7 is a protein that in humans is encoded by the ''SMAD7'' gene. SMAD7 is a protein that, as its name describes, is a homolog of the Drosophila gene: "Mothers against decapentaplegic". It belongs to the SMAD (protein), SMAD family of proteins, which belong to the transforming growth factor beta, TGFβ superfamily of ligands. Like many other TGFβ family members, SMAD7 is involved in cell signalling. It is a TGFβ type 1 receptor antagonist. It blocks TGFβ1 and activin associating with the receptor, blocking access to SMAD2. It is an inhibitory SMAD (I-SMAD) and is enhanced by SMURF2. Smad7 enhances muscle differentiation. Structure Smad proteins contain two conserved domains. The Mad Homology domain 1 (MH1 domain) is at the N-terminal and the Mad Homology domain 2 (MH2 domain) is at the C-terminal. Between them there is a linker region which is full of regulatory sites. The MH1 domain has DNA binding activity while the MH2 dom ...

TGF Beta Receptor 2
Transforming growth factor, beta receptor II (70/80kDa) is a TGF beta receptor. ''TGFBR2'' is its human gene. It is a tumor suppressor gene. Function This gene encodes a member of the serine/threonine protein kinase family and the TGFB receptor subfamily. The encoded protein is a transmembrane protein that has a protein kinase domain, forms a heterodimeric complex with another receptor protein, and binds TGF-beta. This receptor/ligand complex phosphorylates proteins, which then enter the nucleus and regulate the transcription of a subset of genes related to cell proliferation. Mutations in this gene have been associated with Marfan syndrome, Loeys-Deitz aortic aneurysm syndrome, Osler–Weber–Rendu syndrome, and the development of various types of tumors. At least 73 disease-causing mutations in this gene have been discovered. Alternatively spliced transcript variants encoding different isoforms have been characterized. Interactions TGF beta receptor 2 has been shown to i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Knock-in
In molecular cloning and biology, a gene knock-in (abbreviation: KI) refers to a genetic engineering method that involves the one-for-one substitution of DNA sequence information in a genetic locus or the insertion of sequence information not found within the locus. Typically, this is done in mice since the technology for this process is more refined and there is a high degree of shared sequence complexity between mice and humans. The difference between knock-in technology and traditional transgenic techniques is that a knock-in involves a gene inserted into a specific locus, and is thus a "targeted" insertion. It is the opposite of gene knockout. A common use of knock-in technology is for the creation of disease models. It is a technique by which scientific investigators may study the function of the regulatory machinery (e.g. promoters) that governs the expression of the natural gene being replaced. This is accomplished by observing the new phenotype of the organism in question. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gene Knock-out
A gene knockout (abbreviation: KO) is a genetic technique in which one of an organism's genes is made inoperative ("knocked out" of the organism). However, KO can also refer to the gene that is knocked out or the organism that carries the gene knockout. Knockout organisms or simply knockouts are used to study gene function, usually by investigating the effect of gene loss. Researchers draw inferences from the difference between the knockout organism and normal individuals. The KO technique is essentially the opposite of a gene knock-in. Knocking out two genes simultaneously in an organism is known as a double knockout (DKO). Similarly the terms triple knockout (TKO) and quadruple knockouts (QKO) are used to describe three or four knocked out genes, respectively. However, one needs to distinguish between heterozygous and homozygous KOs. In the former, only one of two gene copies (alleles) is knocked out, in the latter both are knocked out. Methods Knockouts are accomplished throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SB-431,542
SB-431542 is a drug candidate developed by GlaxoSmithKline (GSK) as an inhibitor of the activin receptor-like kinase (ALK) receptors, ALK5, ALK4 and ALK7. However, it is ''not'' an inhibitor of anaplastic lymphoma kinase (which are commonly known as ALK inhibitors). In-vitro studies While SB-431542 has not proved directly useful for any clinical application, it is used for several applications in molecular biology. It suppresses the TGF-beta-induced proliferation of osteosarcoma cells in humans. Treatment with SB431542 is a robust, clinically applicable, and efficient system for generating mesenchymal stem/stromal cells (MSCs) from human iPSCs. SB431542 can also be used in combination with LDN193189, CHIR99021 and DAPT to transform astrocytes into neurons. It is also commonly used for immunological studies, for instance as a TGF-β inhibitor to facilitate the generation of dendritic cells from peripheral blood monocytes Monocytes are a type of leukocyte or white blood ...
