FUT8
Alpha-(1,6)-fucosyltransferase is an enzyme that in humans is encoded by the ''FUT8'' gene. This enzyme belongs to the family of fucosyltransferases. The product of this gene catalyzes the transfer of fucose from GDP-fucose to N-linked type complex glycopeptides. This enzyme is distinct from other fucosyltransferases which catalyze alpha1-2, alpha1-3, and alpha1-4 fucose addition. The expression of this gene may contribute to the malignancy of cancer cells and to their invasive and metastatic capabilities. Alternatively spliced variants encoding different isoforms have been identified. Kyowa Hakko Kirin's "Potelligent" platform uses a CHO cell line in which ''FUT8'' has been knocked out to make afucosylated monoclonal antibodies Afucosylated monoclonal antibodies are monoclonal antibodies engineered so that the oligosaccharides in the Fc region of the antibody do not have any fucose sugar units. When antibodies are afucosylated, antibody-dependent cellular cytotoxicity (ADC .... ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kyowa Hakko Kirin
is a Japanese pharmaceutical and biotechnology company under the Kirin Holdings, and is among the 40 largest in the world by revenue. The company is headquartered in Chiyoda-ku, Tokyo and is a member of the Nikkei 225 stock index. History On July 1, 1949 the forerunner of the present company, Kyowa Hakko Kogyo Co., Ltd. is established. Following the merger with Kirin Pharma Co., Ltd., on October 1, 2008 the company changed its name to its present. On July 11, 2014, the KHK subsidiary, ProStrakan Group (based in Scotland), acquired Archimedes Pharma from the Novo Nordisk Foundation for $394 million In 2019, the entity was renamed "Kyowa Kirin Co., Ltd.", replacing its prior name of Kyowa Hakko Kirin Co., Ltd. In November 2022, Kyowa Kirin announced plans to spin its international established medicines portfolio into a new joint venture with German company Grünenthal. Business segments and products * Pharmaceuticals business The company developed a method to make afucosyla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enzyme
Enzymes () are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products. Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts are catalytic RNA molecules, called ribozymes. Enzymes' specificity comes from their unique three-dimensional structures. Like all catalysts, enzymes increase the reaction ra ...

Gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Hamster Ovary Cell
Chinese hamster ovary (CHO) cells are an epithelial cell line derived from the ovary of the Chinese hamster, often used in biological and medical research and commercially in the production of recombinant therapeutic proteins. They have found wide use in studies of genetics, toxicity screening, nutrition and gene expression, particularly to express recombinant proteins. CHO cells are the most commonly used mammalian hosts for industrial production of recombinant protein therapeutics. History Chinese hamsters had been used in research since 1919, where they were used in place of mice for typing pneumococci. They were subsequently found to be excellent vectors for transmission of kala-azar (visceral leishmaniasis), facilitating '' Leishmania'' research. In 1948, the Chinese hamster was first used in the United States for breeding in research laboratories. In 1957, Theodore T. Puck obtained a female Chinese hamster from Dr. George Yerganian's laboratory at the Boston Cancer R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
